Shilld: Visible PAID SHILL badges on X/Twitter
The Shilld extension adds a bold PAID SHILL badge to tweets and profile headers for usernames from a public list.
- Fetches the canonical list from /shills/_all.json (this site).
- Background service worker caches results for 5 days.
- Works on x.com and twitter.com, including dynamic timelines.
- No data leaves your browser.

How it works
A background service worker fetches the usernames list from this site (CORS-safe in the extension context), caches it for 5 days in chrome.storage, and the content script inserts the badge next to usernames in tweets and on profile headers.
