Is ChatGPT Ad Blocker - Block Ads on ChatGPT & AI Chatbots safe?

Low risk

ChatGPT Ad Blocker runs a content script on every website and applies hide/remove rules fetched from its own server every 6 hours.

The extension injects a content script into every page you visit (not just ChatGPT) that hides or deletes DOM elements matching CSS selectors. Those selectors come from a rule set the extension downloads from api.gptadblock.com on a timer, with no signature or integrity check on the response. Only ad-blocking rules for chatgpt.com currently ship, but nothing in the extension limits the domains or selectors a future server response could target.
