_k, did you try to raise an issue? Did you ask Twitter what happened?

Also, this is why Telegram's policy towards "desired username"[1] worries me:

  If your desired username is already taken, we will be happy to help you acquire it, provided that you have that same username on at least two of these services: Facebook, Twitter, Instagram.

No, you don't do that! If someone has taken "tom" and that also happens to be the ID of Tom Hanks or Tom Cruise - everywhere else, they should have come first, or you should have reserved all those famous uesernames hoping these celebrities will come to your service.

I may have tweeted what happened but I didn't raise an issue in an official way.
