The Verge reported on October 17 that a growing list of major websites is shutting out personal AI agents from OpenAI, Meta, xAI and others. Users of services like Meta's Muse, xAI's Grok, OpenAI's Dots and Instinct have reported blocks across top sites in recent weeks. Yelp told TechCrunch it only allows AI agents that have paid for access through its data licensing program, while Delta Air Lines is preventing agents from booking tickets and says it has no partnership or integration that lets a third-party agent shop or book on a customer's behalf.

The reasons sites give are security, licensing and lost advertising revenue — the same fight Amazon picked with Perplexity, now running much broader. Even where agents are not banned outright, they run into anti-bot systems: login screens, CAPTCHAs and device checks treat automated browsers as hostile by default. Some users say eBay suspended their accounts over agent use, and there are unverified reports of blocks at Amtrak and Cars.com.

The standoff follows the big banks' move to keep outside agents out of customer accounts, covered here on October 16. Meta, which ships an agent of its own, argues the other side: turning away a personal agent, it says, "means turning away the customer behind it." How this resolves — paid licensing deals, standards for agent access, or a web that stays closed to software — will shape what the agentic web actually looks like.
