X Filter CN – Chinese spam reply blocker

X Filter CN hides Chinese spam and adult-content promotions on X (Twitter). Built-in rules work as soon as the extension is installed, and you can add keywords, regular expressions, or account filters when needed. 1. Match display names, bios, and post text The extension checks the display name, @handle, public bio, post body, and card text, so promotional text written in a display name or bio can still be detected. 2. Detect common text variations Before matching, the extension normalizes full-width and styled letters, traditional Chinese, zero-width characters, and emoji or decorative symbols inserted inside words. 3. Review what was filtered A control in the lower-right corner shows the number of filtered items. Open it to see the matching reasons, jump to the original post, or restore an individual item. 4. Filter replies by account On post detail pages, replies can be filtered by following count or follower count. Replies from accounts using X's default avatar or without verification can also be hidden. Account filters do not affect the home timeline or original posts. 5. Add and test your own rules Add keywords or regular expressions, disable built-in rules, and test text before saving. Data handling To provide filtering, the extension reads display names, @handles, public bios, profile image URLs, post text, card text, and available following counts, follower counts, and verification status from data X returns to the current page. Direct-message endpoints are skipped. This data is processed only in the current tab's memory and is not stored or uploaded. Rules, toggles, and thresholds are saved in Chrome sync storage and may sync with the user's Chrome account according to Chrome settings. The developer cannot access them. The extension contains no analytics or remote code.
