X (Twitter) Comment Blocker is a free, open-source browser extension that automatically filters spam and bait-account comments on X using a cloud-synced public blocklist plus a customizable local one, with a permanent whitelist and bulk-blocking tools. All filtering happens locally in the browser. It's aimed at X users who want a cleaner comment section without manually blocking spam accounts one at a time.
