Congratulations, Katy Perry, you survived the Great Twitter Purge of 2018.
Despite losing 3 million followers, the singer remained the biggest account on the platform, with 107 million followers overall, following Twitter's removal of "locked" accounts from its follower counts.
Twitter explained Wednesday that locked accounts are different from spam and bot accounts -- two other issues that have plagued the platform -- in that they are usually started by "real people" but that the company is unable to verify they're still being run by their initial creators. The company started axing them on Thursday, and several major accounts saw several million followers vanish in the process.
President Barack Obama lost 2.5 million accounts, falling to 101 million followers. The man that took over his spot in the White House, President Donald Trump, saw his followers decrease by 300,000 between Wednesday and Friday, hitting 53.1 million.
Justin Bieber, the man behind the second most popular Twitter account, also shed 3 million followers, dropping to 104 million followers. Rihanna took a noticeable dip as well, with her follower count falling 2.2 million since Wednesday to 86.8 million.
Twitter had said regular users would likely see a drop of 4 followers or less, but warned celebs could see bigger declines. Vijaya Gadde, Twitter's head of legal, policy, and trust, said on Wednesday the follower purge "may be hard for some, but we believe accuracy and transparency make Twitter a more trusted service for public conversation."
Even the platform itself was hit by the purge, with the official Twitter account losing nearly 8 million followers since Wednesday.
