Instagram confirms that a bug is causing follower counts to change (Updated)

Update: Instagram says the issue will be fixed by 9AM PST on Thursday.

Instagram confirmed today that an issue has been causing some accounts’ follower numbers to change. Users began noticing the bug about 10 hours ago and the drastic drop in followers caused some to wonder if Instagram was culling inactive and fake accounts, as part of its fight against spam.

“We’re aware of an issue that is causing a change in account follower numbers for some people right now. We’re working to resolve this as quickly as possible,” the company said on Twitter.

The Instagram bug comes a few hours after a Twitter bug messed with the Like count on tweets, causing users to wonder if accounts were being suspended en masse or if they were just very bad at tweeting.
