If you build an app on Vercel and one of your users violates Vercel's rules, you are responsible for that violation and must cut off that user's access and report it to Vercel.

This provision places compliance obligations on account holders for conduct they did not directly perform, meaning that inadequate end-user controls can result in account suspension or termination even if the account holder personally did nothing wrong.
Interpretive note: The term 'promptly' is not defined with a specific timeframe, introducing uncertainty about when the notification obligation is triggered and whether a delay could itself constitute a violation.
Developers and businesses hosting applications on Vercel bear liability under this clause for their end users' violations of the AUP, including unauthorized access, spam, malware distribution, or prohibited AI content generation, and must terminate violating users and notify Vercel promptly.

"You are responsible for ensuring that your end users comply with this AUP. If you become aware of any violation of this AUP by an end user, you must promptly terminate that end user's access to your services and notify us.— Excerpt from Vercel AI's Vercel AI Acceptable Use Policy
REGULATORY LANDSCAPE: This provision interacts with the FTC Act's framework on unfair and deceptive practices by establishing a contractual chain of responsibility that may factor into regulatory assessments of whether a platform operator took reasonable steps to prevent prohibited conduct. It also engages the Computer Fraud and Abuse Act and CAN-SPAM Act in scenarios where end-user violations involve unauthorized access or unsolicited communications. EU compliance teams should consider whether this contractual obligation aligns with GDPR Article 28 processor obligations and the EU AI Act's requirements for deployers of AI systems. GOVERNANCE EXPOSURE: High. This clause creates direct contractual liability for account holders based on third-party conduct, and the obligation to promptly terminate end-user access and notify Vercel requires operational monitoring and incident response capabilities that many smaller developers or businesses may not have in place. The absence of a defined timeframe for 'promptly' introduces interpretive uncertainty about when notification obligations are triggered. JURISDICTION FLAGS: EU and EEA customers face heightened exposure because GDPR and the EU AI Act independently impose obligations on deployers of AI-enabled applications regarding user conduct and content. California-based customers should assess whether this provision interacts with California consumer protection statutes. Organizations serving minors face additional exposure under COPPA if end-user violations involve minor-directed content or data collection. CONTRACT AND VENDOR IMPLICATIONS: Procurement and legal teams should ensure that downstream end-user agreements for applications hosted on Vercel incorporate equivalent AUP obligations, creating a contractual pass-through that reduces the gap between Vercel's expectations and the account holder's legal relationship with their own users. B2B customers should assess whether their own vendor agreements with Vercel adequately address incident response timelines and notification obligations. COMPLIANCE CONSIDERATIONS: Compliance teams should audit whether their current end-user agreements, terms of service, and content moderation policies cover all categories of prohibited use listed in Vercel's AUP. Organizations without existing user monitoring or abuse reporting mechanisms should evaluate whether such mechanisms are required to meet the 'promptly terminate and notify' standard this provision establishes.
