Banned Hashtag Checker
Check hashtags against a known banned list before posting — avoid shadowbans on Instagram and TikTok.
Static lookup list — not exhaustive. Instagram and other platforms may shadowban additional tags.
About this tool
Using banned or restricted hashtags can suppress reach on Instagram and TikTok — sometimes without notification.
Cross-check your tag set against a known banned list before every post in sensitive niches.
How to use the Banned Hashtag Checker
- 1
Paste your caption or list of hashtags into the checker.
- 2
Review any tags flagged as banned or restricted.
- 3
Remove flagged hashtags before publishing to protect reach.
Limitations
Platform ban lists change frequently — this static checker is a safety net, not a guarantee.
Context matters — some tags are banned only in certain combinations or regions.
Pro tips
- Remove flagged tags rather than swapping similar risky alternatives.
- Prefer 3–5 highly relevant tags over maxing out hashtag count.
