The Rise and Fall of Twitter's Blue Check Verification System.

Twitter users who lost their blue check marks on the site appear to have found a way of bringing their verified checks back without giving in to Elon Musk’s $8-a-month demands by adding the phrase “former blue check” to their Twitter bios, though the trick doesn’t seem to work for accounts that have never been verified. However, some users also said their restored blue checks quickly vanished after trying the hack, suggesting the quirk is more likely to be an error rather than an Easter egg intentionally embedded in Twitter’s code.
