Yes, ad blockers are legal in Washington under current state law, but their use is constrained by federal regulations and evolving digital privacy standards. Washington’s Consumer Protection Act (RCW 19.86) does not explicitly prohibit ad blockers, yet businesses may pursue claims under deceptive practices if ad blocking interferes with contractual terms or disrupts services. The Washington State Attorney General’s Office has not issued formal guidance on ad blockers, leaving enforcement to federal frameworks like the Computer Fraud and Abuse Act (CFAA) and the Digital Millennium Copyright Act (DMCA). As of 2026, compliance risks may intensify if the state adopts stricter digital accessibility or anti-interference rules, particularly for publishers relying on ad revenue.
Key Regulations for Ad Blockers in Washington
- Federal Anti-Circumvention Laws: The DMCA prohibits bypassing technological measures (e.g., ad-blocking scripts) that control access to copyrighted content, exposing users to potential liability if ad blocking violates a website’s terms of service.
- Washington’s Unfair Business Practices Act: RCW 19.86.020 could apply if ad blocking is deemed deceptive or unfair, particularly if it misleads users about service functionality or violates contractual agreements with publishers.
- Terms of Service Enforcement: Websites may pursue civil claims under Washington contract law for violating anti-ad-blocking clauses, as seen in recent litigation involving Seattle-based media outlets enforcing such policies.
