You do have a knack for easy target threads don't you... never mind that and don't feed the others, don't get defensive.
In response to your initial querry. ZAM and all other fansites have nothing to do with SE. Chances are 1 of 2 things, you either logged into XIV from a different IP address (or tried to access the official forums possibly from work or a library etc...) OR some one tried to access your accounts. If you didn't access XIV or the official SE forums, then I would strongly suggest you look into purchasing a security key from SE.
