Account got deleted?

So I was playing last night with a friend and I was trying to play again just now. I couldn’t sign in. I ended up trying to recover my password and it says my account doesn’t exist. So I remade my account. I think I made it about a month or two again. Just wondering why I got deleted.

What’s your old account name?

This same name. Under the same email. The emails don’t seem to mention my previous username. I don’t really think I lost anything, but just wondering why.

Not too sure what happened to be honest, there are (or have ever been) no other accounts with this name…
If this account works though I wouldn’t mind too much.
