Elon Musk’s Twitter on Thursday began a purge of blue verification checkmarks from users who have not signed up for its subscription service, with the checks disappearing from the accounts of journalists, academics and celebrities.

The blue checks even disappeared from the accounts of some of the most well-known and widely followed people on the social network, including Kim Kardashian, Beyonce, former president Donald Trump and Twitter founder Jack Dorsey.
