"I've been shadowbanned" is the most common complaint on Instagram. Usually, something else is going on.
What it actually is
Instagram can limit recommendations for content that breaks recommendation guidelines. You can check under Settings → Account status. If it says you're eligible for recommendations, you're not restricted.
Common real causes of reach drops
- Posting less often
- Content that doesn't hold attention
- Copyrighted music on business accounts
- Reposted content with watermarks from other apps
- Seasonal dips
Fixes
- Check Account status
- Post original reels consistently for two weeks
- Use trending audio available to your account type
- Remove posts that were flagged
Reach usually recovers once content performance does.
