Twitter today announced it’d be removing locked accounts from users’ follower counts. If you’ve noticed a precipitous drop in follower counts today, it’s not you — it’s your followers.

Reports surfaced earlier this week that Twitter had suspended a multitude of fake accounts in the months of May and June — apparently in an attempt to curb the rise of bot and their accompanying cocktail of issues. The number of accounts targeted is reportedly around 70 million.
