Hey Pokemaster, can you change this person's username?

Question

Hey, you should really change Polite Patamon's username.

Here's a bit of backstory for this guy:
He came on the DB Showdown server one day to spam profanities and attempt to troll people, I was one of the only users online and he became obsessed with me or something, so he clicked the link to this site, made an account, and used my PS username (Polite Patamon). He was immediately banned for doing the same nonsense here.

It's been this way for years now and I never really said anything about it, but I would like his name to be changed to avoid confusion with me, and to allow me to change back to that username in the future. Thanks!

I'm pretty sure that if you change name and someone takes your old name then it's fair game unless it's Auth

It's fair game if it happens by coincidence, but this person clearly did it to be a nuisance. (And to anyone who is concerned over the truth of the story: I know for a fact that it's real.)
Pokemaster's call though.
