Terminating an account to create a new one

I haven’t played on this server (or Terraria at all as a matter of fact) for years. I’m looking to come back to the game and the server with a fresh start. I’m having trouble registering a new character (under a different name) and I kind of want to get away from this pile of cringe that I once called an account. Is there any this account can be terminated so I can start again? Thanks in advance.

Do you, uh, have to make 2 threads?

I ended up somehow posting twice due to a bug
