ClankerBlocker is a fake-follower and bot checker for X (Twitter). It scans your Following and Followers lists, scores every account against six documented signals, and exports a CSV cut/block list. Read-only — it never unfollows, blocks, or posts for you.
Invite-only beta. Join the waitlist or sign in if you already have access.
No hidden model, no vibes-based ban list. Every point traces back to a check — and the breakdown ships with the row.
Verified accounts get a 10-point credit against flags they trip. Verification isn’t proof — it’s one more input in the same evidence trail.
Scan Following or Followers, filter with structured criteria, label accounts Keep/Review/Cut, export cut or block lists. Continuous evidence, not a one-time badge — health tracking shows what moved between scans.
Estimates vary widely — which is exactly why per-account evidence beats a single platform-wide number.
