X Blocker - Auto-Detect & Bulk Block Spam

Automatically flags spam accounts on X (Twitter) by keyword or regex, then blocks them in bulk after you confirm.

X Blocker adds a one-click block button to every post on X (Twitter), plus keyword/regex scanning that batch-blocks spam, scam, and harassment accounts - with your confirmation before anything happens. WHY X's own "Block" and "Mute" only work one account at a time. If you're dealing with recurring spam patterns - crypto and token promotions, adult solicitation spam, unsolicited ads and product pitches, engagement-farming replies, harassment campaigns - clicking through "... > Block > Confirm" for every single account doesn't scale. FEATURES - One-click block: a small icon next to every post's action bar blocks the author instantly. - Keyword and regex batch blocking: match against post text, display name, handle, or bio. Matches show up in a review list; you confirm before any block happens (fully-automatic mode is available but off by default). - Obfuscation-resistant matching: built-in patterns tolerate spammers inserting spaces, emoji or invisible characters between letters. - Built-in default filters for common solicitation spam, fully editable. - Allowlist: handles you never want blocked, even if they match a keyword. - Throttling and backoff: configurable delay, jitter and per-run cap, with automatic exponential backoff on rate limits. - Action log with one-click undo: every block is logged with the matched rule, so misfires can be reversed instantly. - Auto-cleanup: once an account is blocked, their posts and replies disappear from the current page immediately (optional). - Fully localized interface: English, Simplified Chinese, Traditional Chinese, Japanese, Korean, Spanish, Portuguese and Indonesian. - Draggable floating panel that remembers its position, and only appears on pages that actually show posts. PRIVACY No account, no API key, no backend server, no analytics. The extension calls the same internal endpoints X's own website already uses, with your existing logged-in session. All filters, settings and logs are stored locally in your browser only.
