Just came back and found unknown login accounts

[Vixi]

I haven't played here since like 2011 and I decided to play again. I had to get everything reinstalled which includes resetting my passwords again since I forgot all that. My email was still the same so that's fine. So I go to forums and check to see if I still had my old login account. Oddly enough my login account isn't there, but there's 2 unknown login accounts on there. It says they were played in 2014. That's impossible. How did they get there? lol
