Short answer

A sudden follower drop usually comes from Instagram removing fake or inactive accounts, a temporary display bug, or a hacked account that unfollowed or blocked people. Check Where you're logged in and recent activity first. If you see logins or changes you did not make, secure the account. If not, wait a few days and compare counts.

Summary
  • Instagram regularly removes fake and spam accounts, which lowers follower counts.
  • Display bugs can show the wrong count for a day or two.
  • A hacker can mass-unfollow, block or remove followers.
  • Check login activity before anything else.
  • Bought followers are often removed in purges.

#Why did I lose followers suddenly?

CauseSignsWhat to do
Fake account purgeDrop of a few percent, no strange activityNothing; your real audience is intact
Display bugCount changes back and forth, others see a different numberWait 24 to 72 hours
Hacked accountLogins you don't recognise, follows or posts you didn't makeSecure the account now
Bought followers removedLarge drop after a purchaseStop buying; it risks the account

#How do I check if I was hacked?

  1. Open Accounts Center, Password and security, Where you're logged in.
  2. Remove any device you don't recognise.
  3. Check Your activity for follows, unfollows or blocks you didn't make.
  4. Change your password and turn on two-factor authentication.
  5. Check the email and phone on the account are still yours.

#Will my followers come back?

Followers removed in a fake account purge do not come back, because those accounts are gone. Display bugs usually correct themselves. People a hacker unfollowed or blocked need to be followed or unblocked again.

#What common mistakes should I avoid?

  • Using a who-unfollowed-me app that asks for your password.
  • Buying followers to replace the lost ones.
  • Assuming it's a bug and ignoring unknown logins.
  • Posting angry complaints instead of checking activity.

#When should I ask an expert before I act?

Ask for help before you appeal if the account matters to your income, your business or your memories, if you have already had one appeal rejected, or if you cannot tell whether the problem is a bug, a restriction or a hack. That is where most avoidable losses happen.

Removing fake accounts does not penalise you.
Should I contact Instagram?
