@CrazyMausi2000,
There's a
CrazyAdviser here, is that the one you mean?
Not that I can think of any obvious explanation.. if you can login to that account as well because it's a username you tend to use + you know the password, then the only logical explanation would seem to be that you made it. :-)
Hypothetically, of course, somebody who knows the kind of usernames you tend to make
and knows your password could have made it.. but why?
