One of the world’s foremost tweeters just lost hundreds of thousands of followers in a matter of hours.

Following Twitter CEO and Cofounder Jack Dorsey’s announcement that the popular social media platform would begin purging locked accounts, U.S. President Donald Trump lost 300,000 followers in less than a day.

The president still boasts approximately 53.1 million followers on the social media platform.

Trump was just one of many notable public figures who shed thousands of Twitter followers

The recent move by the social media titan is part of a broader strategy to try to eliminate fake accounts, trolls, bullies and users accused of hate speech and manipulating the social media channel for political causes.

The company also recently unveiled a global campaign to develop ‘Twitter Health Metrics’ based on public input. The campaign’s goal is reportedly to improve oversight of the social media platform and to better combat anti-social and harmful behavior on it by malicious users.

In early March 2018, Dorsey publicly acknowledged that his company was complicit in the ‘negative consequences’ of malicious users and vowed to engage the public in order to develop ‘holistic and fair solutions’ to the problem.

We’re committing Twitter to help increase the collective health, openness, and civility of public conversation, and to hold ourselves publicly accountable towards progress. — jack (@jack) March 1, 2018

Why? We love instant, public, global messaging and conversation. It’s what Twitter is and it’s why we‘re here. But we didn’t fully predict or understand the real-world negative consequences. We acknowledge that now, and are determined to find holistic and fair solutions. — jack (@jack) March 1, 2018

On July 11, Dorsey announced the first step in the social media platform’s widespread crackdown on harmful behavior: removing locked accounts whose users were thought to have engaged in suspicious activity.

This week we’ll be removing locked Twitter accounts (locked when we detect suspicious changes in behavior) from follower counts across profiles globally. The number of followers displayed on many profiles may go down. #health https://t.co/JGmE4ofoZ2 — jack (@jack) July 11, 2018

The global purge caused the President’s number of Twitter followers to drop by 100,000 just a few minutes, eventually falling by 400,000 within a few hours of Dorsey’s public announcement.

Trump reportedly regained approximately 100,000 additional followers shortly afterwards however.

The U.S. president is far from the only notable public figure to lose hundreds of thousands or even millions of Twitter followers within a short time span. Popular celebrities that have reportedly lost followers include Justin Bieber, who lost 2.7 million followers and Taylor Swift, who shed about 2.3 million followers on the social media platform.

Rihanna also reportedly lost 605,000 followers.

A number of prominent U.S. politicians also shed a significant number of Twitter followers in the wake of the social media channel’s widespread purge. Former President Barack Obama, the most-followed current or former head of state on the platform, lost approximately 2.3 million followers quickly, dropping his official count to about 101.3 million.

In addition, Congressional leaders in Washington, D.C. also saw losses on a smaller scale.

House of Representatives Speaker Paul Ryan shed about 40,000 followers while his Democratic counterpart Minority Leader Nancy Pelosi lost roughly 17,000 followers.

In the Senate, Republican Majority Leader Mitch McConnell lost roughly 2,400 Twitter followers and Chuck Schumer, the Minority Leader of the chamber, lost about 7,000 followers.
