Seems there's some debate about this account being Elon or not.

Adrian, in a group voice call, referred to himself as being the subject of people who have a problems with anything Elon or Elon-like people. Saying "Given I was the first thing she posted about".

Seems he may be Elon, he may be trolling trying to make us think he's Elon. His voice sounds a lot like Elon's, but could easily be explained by AI voice changers if he's committed enough. That's what I found from a quick Google anyway.
