NEW YORK: Elon Musk's X, the platform formerly known as Twitter, has begun restoring complimentary blue checks for some of its users, the latest unexpected shift to cause a lot of confusion on the platform.

For years, Twitter’s blue checks mirrored verification badges that are common on social media, largely reserved for celebrities, politicians and other influential accounts. That changed months after Musk bought the platform for US$44bil in October 2022.
