President Donald Trump, one of the most prolific and high-profile tweeters, lost about 100,000 of his approximately 53.4 million Twitter followers, according to the Washington Post, and former President Barack Obama lost about 400,000 from his 104 million followers.
"This week, we'll be removing these locked accounts from follower counts across profiles globally", said Twitter. While it excludes spam accounts in reported user data, Twitter noted early this year that monthly active user numbers would be "negatively impacted" by efforts to expunge fake accounts.
Other regular Twitter users have noticed their accounts dropping today thanks to the purge, while others didn't notice a change at all to their accounts.
The new policy could be substantial for some Twitter users because follower totals serve as a top selling point when celebrities and so-called social media influencers negotiate deals with advertisers.

Meanwhile, Mr. Obama lost about 2 million, leaving him with 101 million overall. Twitter locks accounts when they display a sudden change of behaviour, like sending lots of unsolicited replies.
