Major websites are blocking AI agents (Muse, Dots, Grok, Perplexity)
Multiple popular websites and services are preventing autonomous AI agents — including Meta’s Muse, OpenAI’s Dots, xAI’s Grok, Instinct, and Perplexity — from performing tasks like shopping, booking, and account access. Companies such as Amazon, Yelp, airlines, banks, and Cloudflare’s anti-bot tools are cited as blocking agents or requiring paid data licensing, while some retailers (Walmart, Gap, Sephora, Best Buy, Shopify merchants) have partnered to allow agent access.
