Yes, I have used my GSC password at other sites. I may have used it at TSR when I was there too, but I since changed it.
You changed your password at TSR or at GSC?
I’m asking because since the hacker used your password to get into GSC the most important thing would be to establish how he/she got hold of it.
Try to think: Did anyone else know your GSC password? Or could anyone have guessed it? Those other places you used it, are they secure or could the breach have happened there?
And one more thing: That admin that you fell out with and who then moved to TSR. Is/was he in any way close to or friends with Atwa? I know you aren’t familiar with Atwa, but maybe you could PM Coconut with the name of this admin, and she could let you know if there is any connection between the two. That could be another important clue.
It’s puzzling. So far I don’t see a firm TSR connection, except that what happened at GSC – the name change, the deletion of everything and particularly the PM to Scotty calling him a Gay Pirate Fag – is exactly the kind of thing that Atwa would do.
