Changing your twitter display name should arguably immediately in software invalidate your blue-tick ""verification"" just as you can't rename a website without getting a new certificate. Of course, the real problem is that the blue tick is both arbitrary and meaningless!

This would've also caught the UK conservative party's trick where they set their Twitter name to "Fact check UK" or similar during a debate. Clever but morally reprehensible.
