How to check for a shadowban on X without lying to yourself

Start with a public username lookup. If the handle does not resolve, there is no visibility question yet; you first have an identity question.

Then compare historical profile stats against current public timeline evidence. If the account reports prior activity but current public probes look empty, that is a stronger signal than a raw drop in impressions.

The practical workflow

1. Confirm the username resolves publicly.
2. Check whether the account is protected or public.
3. Inspect whether public tweet probes return visible entries.
4. Check whether profile and search-style routes are reachable.
5. Review the result with confidence, not false certainty.

This is exactly why a confidence-based checker is more useful than a binary yes-or-no badge.
