Celebrities, professional athletes and other high-profile Twitter users are once again being verified by the social media platform and they don’t know why the blue check marks reappeared — nor do they seem too happy about it. Twitter removed the blue check icons last week from accounts that don’t pay the new $8 monthly fee, but the marks mysteriously returned over the weekend for many highly followed accounts. Some users, including rapper Lil Nas X, are disavowing what’s become a divisive symbol of Twitter owner Elon Musk's erratic changes to the platform, posting that they didn’t pay to get their blue check back.
