Prepared by UNO | April 25, 2026 | Ohio Q3 Launch Scope: Legal risk assessment of using listing inquiry channels for seller acquisition
Framing A — entering as a buyer-shaped inquiry and pivoting to a sales pitch — carries real deceptive-practice risk under Ohio CSPA ORC 1345.02 and the FTC Act Section 5 impersonation standards, and it is a clear violation of Zillow's TOS prohibition on misrepresenting affiliation or making representations under false pretenses. Framing A should not ship. Framing B — identifying Agent9 transparently in the first sentence of the same channel — is legally cleaner on the deception front, but still violates Zillow's "personal, non-commercial" use restriction and runs meaningful TOS-account-termination risk if deployed at volume. The safest operational posture for v2 is to use the inquiry channel only in Framing B for low-volume relationship pilots (Houzeo, Craigslist, direct FSBO platforms) where TOS enforcement appetite is low and no pretense is involved — not at 1,000-inquiry scale on Zillow. The one attorney memo needed is a narrow Ohio real-estate-attorney review of Framing B copy against CSPA and ORC 4735.02 unlicensed practice risk: estimated $400–600, one engagement.
Zillow's direct TOS pages block fetch (403 enforcement), but the operative language is confirmed from multiple secondary sources and Zillow's own search-indexed content:
Confirmed prohibited-use clauses (Zillow Terms of Use, last updated October 2025):
"You may not use any robot, spider, scraper or other automated means to access the Services for any purpose without our express written permission." — Kills bulk inquiry automation outright.
"All information obtained from Zillow, Inc. will be used solely for your personal, non-commercial purposes." — The MLS/VOW data-use restriction. B2B prospecting is explicitly commercial.
"Impersonate another person, misrepresent your affiliation with another person or entity, or make any representation to any third party under false pretenses." — This is the Framing A kill shot. Sending an inquiry structured to appear as a buyer inquiry when the actual purpose is B2B solicitation is a representation under false pretenses.
Sources: Zillow Group Terms of Use (zillowgroup.com/terms-of-use, redirects to zillow.com/z/corp/terms/); confirmed from Zillow NMLS Data Terms; HomesUSA.com analysis of January 2021 Zillow TOS rewrite (terms materially unchanged on prohibited uses since then per indexed content).
Verdict for Zillow:
Realtor.com TOS was not directly fetchable, but from prior research and search confirmation: Move Inc. prohibits "automated data extraction, crawling, and bots" and any access without express written permission. The contact inquiry channel on Realtor.com routes through the listing agent's registered contact, not directly to the seller. In practice, a B2B inquiry sent through Realtor.com's "Contact Agent" form reaches the listing agent's inbox, not the seller. The seller is rarely in the Realtor.com contact loop. This makes the channel structurally less useful for direct seller outreach and the TOS exposure largely academic — you would be pitching an agent, not a seller.
Verdict for Realtor.com: Channel does not effectively reach sellers for agent-listed properties. Same commercial-use TOS prohibition applies. Not a useful channel for the stated purpose.
MLS IDX contact channels are behind broker-website implementations. There is no uniform MLS "inquiry button." Each broker's website has its own TOS. The standard IDX data-use restriction (NAR Policy 7.58) limits display to legitimate buyer use, not B2B prospecting. No direct MLS inquiry channel is publicly accessible to Agent9 without a broker partnership.
Ohio CSPA (ORC 1345.02) prohibits any supplier from committing an "unfair or deceptive act or practice in connection with a consumer transaction." Ohio courts and the Ohio AG apply the FTC's materiality standard: a deceptive act is one that has the "tendency or capacity to mislead consumers concerning a fact or circumstance material to a decision to purchase." Ohio courts give great weight to FTC orders and interpretations under ORC 1345.05(B)(2).
Is a seller in a "consumer transaction"? Yes, if they are being solicited to purchase Agent9's services. Agent9 is the supplier; the seller is the consumer. The CSPA applies.
Structure: Inquiry is submitted through Zillow's "Contact Agent" or equivalent FSBO contact form. The inquiry text is written to appear as buyer interest ("Saw your listing, have some questions..."). Once the seller responds, the conversation pivots: "By the way, have you heard of Agent9?"
Ohio CSPA analysis: This framing creates a false impression material to the seller's decision to engage. The seller opens the conversation believing they are responding to a buyer. The initial misrepresentation is what induces the engagement — without it, the seller would not respond. Ohio ORC 1345.02(A) covers unfair or deceptive acts regardless of whether they occur "before, during, or after the transaction." The deception occurs at the solicitation stage, which is covered.
The Ohio AG's guidance on CSPA makes clear that "creating a false impression" through omission or misleading framing is actionable even without an explicit false statement. Framing A creates a false impression about the identity and purpose of the contact.
FTC Act Section 5 analysis: The FTC's 2025 Impersonation Rule (16 CFR Part 461, effective March 2024, currently in litigation but operative) targets schemes that impersonate individuals or entities to induce engagement. Framing A impersonates a prospective buyer. The FTC has issued multiple enforcement actions in 2025 against impersonation schemes in consumer contexts. No specific real estate cold-outreach enforcement action was found, but the analytical framework applies cleanly.
Verdict — Framing A: Carries real CSPA deceptive-practice exposure. The misrepresentation is material (it induces engagement that would not otherwise occur). It additionally violates Zillow's TOS. This is the higher-risk path. Do not ship Framing A.
One honest caveat: Actual enforcement against a startup sending a few hundred B2B inquiry messages is unlikely to come from the Ohio AG or FTC — those bodies pursue patterns, class-action plaintiffs, and large-volume campaigns. The more realistic enforcement vector is: (1) Zillow account termination, (2) a class action brought by a plaintiff's attorney who signed up as a seller contact and received deceptive solicitations, citing Ohio CSPA class-action standing under ORC 1345.09(B). That last risk is low but non-zero and grows with volume.
Structure: "Hi, this is the Agent9 team — an Ohio FSBO platform. We saw your listing and wanted to introduce our services. [Brief value prop. Opt-out mechanism.]"
Ohio CSPA analysis: No false impression is created about identity or purpose. The solicitation is commercial, but commercial solicitation is not per se deceptive under CSPA. The CSPA risk remaining in Framing B is the content of the pitch — any false claim about Agent9's capabilities, market data, or results would be actionable (e.g., "90% of Agent9 sellers close faster than with an agent" without data). Clean factual copy eliminates this risk. The CSPA does not prohibit unsolicited B2B outreach; it prohibits deceptive content in such outreach.
FTC unfair-and-deceptive-acts analysis: No deception in identity or purpose. FTC Section 5 is not triggered. CAN-SPAM compliance required for email (see existing compliance map).
Ohio Real Estate Commission rules: ORC Chapter 4735 governs licensed real estate activity. It does not prohibit a non-licensed party from sending marketing communications to sellers. The risk is unlicensed practice (ORC 4735.02), which applies only if Agent9's pitch involves property-specific advice, pricing guidance, or negotiation assistance — not if it is a straightforward "here is a tech service subscription" pitch. Framing B as a software/communications service presentation does not implicate ORC 4735.02.
Verdict — Framing B: Legally clean on deception. Clean on Ohio CSPA if copy is factual. Clean on FTC standards. Not clean on Zillow TOS (commercial use restriction remains). The OREC rule does not apply. This is the path to adopt for v2 — but the channel matters. Framing B on Zillow at scale still triggers account-termination risk.
The listing's contact channel is publicly posted and solicited by the seller or their agent. When a seller lists on Zillow, they activate a contact form inviting inquiries. The seller (or their agent on their behalf) has expressly held out that form as a channel for inbound communication. Contacting a seller through a channel they themselves activated is meaningfully different from unsolicited outreach to a private address. Under the tortious interference framework, one element is "improper means" — using the seller's own solicited channel is less "improper" than cold-dialing a private number or mailing a home address obtained from auditor records. The argument is that going through the published inquiry channel reduces the "improper means" showing.
Additionally, the contact channel is structural to the listing platform, not tied to the exclusive agreement itself. Using the inquiry channel does not inherently target the listing broker's relationship — it targets the seller as a property owner. The exclusive listing agreement governs the broker's right to compensation, not the seller's right to receive communications through public channels.
The tortious interference analysis does not turn primarily on the channel — it turns on the content and intent of the communication. If Agent9's message says or implies "cancel your agreement and use us instead," the channel used is irrelevant to the interference element. A polite Zillow inquiry that says "why pay agent commissions when you can use Agent9?" is still a pitch to abandon the listing relationship, regardless of how it was delivered.
Furthermore, the listing agent — not the seller — controls and monitors many inquiry channels on agent-listed properties. Sending a B2B solicitation through an agent-managed contact form creates a different problem: the agent receives it, not the seller. This blunts any outreach effectiveness and may provoke an agent complaint to Zillow rather than a legal action.
The verdict on tortious interference channel argument: Going through the solicited contact channel provides modest but real mitigation on the "improper means" element — probably enough to further reduce what was already a low-to-medium litigation risk for broad-based outreach. It does not eliminate the risk if the message content explicitly pitches contract cancellation. The same content framing controls from the v1 plan apply: pitch "when your current listing expires, consider Agent9" rather than "cancel your Realtor agreement now."
The 2026 NAR Code of Ethics Article 16 states verbatim: "REALTORS® shall not engage in any practice or take any action inconsistent with exclusive representation or exclusive brokerage relationship agreements that other REALTORS® have with clients."
The NAR Code of Ethics expressly applies only to REALTORS® — NAR member licensees. The Code's preamble states that REALTORS® "voluntarily accept" these obligations. It does not purport to bind non-members or non-licensees.
SOP 16-2 is the most relevant standard: it permits general announcements to prospects even if some have exclusive agreements elsewhere, but prohibits targeted solicitation using MLS listings or "Contact Agent" form data as the source. This is a rule for REALTORS®, not for Agent9.
SOP 16-3 allows contact for different service types unrelated to current services — but again, this is a permission granted to REALTORS® who would otherwise be prohibited. It does not define what non-licensees can or cannot do.
The practical answer to Question 4: NAR Article 16 does not apply to Agent9. Agent9 is not a REALTOR®, is not an NAR member, and is not subject to NAR ethics enforcement. No Ohio Real Estate Commission rule was found that extends NAR Article 16 restrictions to non-licensed third-party tech companies.
The relevant legal framework for Agent9 is entirely civil law (tortious interference, CSPA) and platform TOS — not NAR ethics. This is actually favorable: the industry norm that "you can't contact active listing sellers" is a rule that governs licensees, not tech companies. Agent9 is in a different regulatory category.
One gap: Ohio REALTORS® association rules and local MLS rules sometimes incorporate Article 16 by reference for participants. If Agent9 ever becomes an MLS participant (through a broker partner), those rules would extend. Until then, no.
Framing B (transparent identification) is the correct path. The v2 plan should:
Drop Framing A entirely. The pretextual buyer persona is a TOS violation on Zillow, a deceptive-practice exposure under CSPA, and an operational liability if any seller or their attorney documents the pattern. The incremental response rate gained by disguising the pitch as buyer interest is not worth the legal posture it creates.
Use Framing B on channels with low TOS enforcement risk. Craigslist FSBO listings (where contact info is publicly posted), ForSaleByOwner.com, Houzeo, and direct county-auditor-derived outreach are the right channels for transparent inquiry outreach. On these platforms, an Agent9-branded inquiry ("Hi, this is Agent9, an Ohio FSBO platform — we saw your listing...") is not pretextual, and the TOS enforcement risk is significantly lower than Zillow.
Do not run 1,000 Zillow inquiries per week under either framing. See Question 6. Even Framing B violates Zillow's commercial-use TOS and will trigger account suspension before it generates meaningful seller engagement.
Subject: Agent9 — A note about your listing at [Address]
Hi [First Name or "there" if unknown],
I'm reaching out from Agent9, an Ohio platform that helps home sellers manage buyer communications and transaction coordination without full agent commissions.
We noticed your listing and wanted to introduce ourselves. If you're exploring your options — especially as you approach the end of your current listing period — we'd welcome a short conversation.
No pressure. If this isn't relevant right now, no reply needed.

Why this copy is clean:
One engagement with an Ohio real estate and consumer-law attorney to review:
Estimated cost: $400–$600 for a focused one-hour memo. No Ohio real estate attorney engagement was found at sub-$400. Suitable firms: any Ohio real estate litigation boutique or consumer law firm that handles CSPA compliance. One flat-fee memo closes residual risk before volume outreach begins.
Zillow's "Contact Agent" button does not route directly to the seller on agent-listed properties. It routes through Zillow's Premier Agent lead-routing system, which assigns the lead to a Premier Agent subscriber (a paying agent) rather than the listing agent. Zillow's own help documentation confirms: "When an interested buyer clicks 'Contact Agent,' they will be connected with our team..." followed by buyer-agent matching. This means on agent-listed properties, Agent9 cannot reach the seller via the Contact Agent button — it reaches Zillow's lead routing system.
On FSBO listings posted by sellers directly, the contact channel may go more directly to the seller's registered email. But FSBO volume on Zillow in Ohio is approximately 769 listings statewide — not a 1,000/week target.
No public documentation of Zillow's specific inquiry rate limits was found. Zillow has stated it "monitors activity in a number of different ways" and removes fraudulent behavior. Third-party experience from BiggerPockets investor forums indicates that inquiry activity is monitored and accounts showing non-buyer patterns (rapid multi-listing inquiries, templated messages) are subject to detection. Zillow runs Imperva WAF infrastructure (confirmed in prior research) which includes behavioral fingerprinting beyond standard rate limiting.
Realistic operational ceiling: For a single Zillow account, sending more than 5–10 templated inquiries per day to different listings without legitimate buyer behavior patterns (browsing, saving homes, etc.) is likely to trigger Imperva behavioral detection and Zillow's internal anti-spam review. At 1,000 inquiries in a week, account suspension is near-certain. Even at 100 inquiries in a week from a single account with non-buyer patterns, the risk is high.
Multi-account workaround: Creating multiple Zillow accounts to distribute inquiry volume is a separate TOS violation (account circumvention) and raises CFAA exposure (evasion of access controls). This path is not viable.
Bottom line on volumetric Zillow use: 1,000 Zillow inquiries in a week is not operationally viable under any framing. Zillow is not the right channel for Agent9's seller acquisition at volume. The county auditor pipeline, direct FSBO platform outreach, and content/SEO inbound (from the existing v1 stack) are the correct high-volume channels.
| Issue | Framing A | Framing B |
|---|---|---|
| Zillow TOS — misrepresentation clause | Violates | Clean |
| Zillow TOS — non-commercial use clause | Violates | Violates |
| Ohio CSPA ORC 1345.02 — deception | Exposure (false impression) | Clean if copy is factual |
| FTC Section 5 — unfair/deceptive | Exposure (impersonation) | Clean |
| Tortious interference — active listing | Medium (channel mitigates slightly) | Low (if no breach-inducement copy) |
| NAR Article 16 | Does not apply to Agent9 | Does not apply to Agent9 |
| ORC 4735.02 — unlicensed practice | Not implicated by channel choice | Not implicated if pitch = software service |
| Zillow volumetric viability at 1,000/wk | Account termination certain | Account termination near-certain |
No Ohio case law found specifically addressing a non-licensed tech company using listing inquiry channels for B2B solicitation. The CSPA and tortious interference analysis is based on general Ohio framework, not directly on-point precedent.
Zillow TOS fetch blocked (403): The prohibited-use clauses quoted above are confirmed from Zillow's search-indexed content and secondary legal analysis sources, but were not directly read from the live TOS page due to Zillow's bot-blocking. The "personal non-commercial" and "false pretenses" prohibitions are corroborated by multiple independent sources and are almost certainly current, but the exact section numbers and surrounding context were not verified from the live document. Re-verify before acting: review the TOS manually at zillow.com/z/corp/terms/ before any inquiry campaign.
Realtor.com inquiry routing: Research confirms the "Contact Agent" form on Realtor.com routes to listing agents, not sellers directly. This assessment has not been independently verified against Realtor.com's current UI for all listing types.
FTC Impersonation Rule status: The FTC's 2025 Impersonation Rule was operative as of April 2026 but faced ongoing litigation. Its applicability to B2B solicitation disguised as buyer inquiry has not been tested in published enforcement or court decisions. Analytical application here is the author's assessment, not settled law.
Ohio Chapter 4719 email scope: Confirmed that Chapter 4719 (telemarketer registration + $50K bond) applies to telephone solicitations, not email. This was not re-verified for any recent legislative amendment in 2025–2026. Confirm before the v2 attorney memo engagement.
