How to report unauthorized access of account?

[PharisHanasaki]

I'd be very surprised if those types of 'hackers' would edit forum posts. This feels more like a prank by someone the OP allows access to the PC or account.

I'm not saying the hackers that get these credentials list use them. They publish them, you can try and find it.
And yes, probably someone close to the OP did it.

You asked how they got her username, I simply stated how easy that was.

Yeah, that would be quite a few people. I'll figure it out and deal with it.

Someone's got to be a special kind of loser to hack a forum account of all things.

My condolences. And unfortunately, I doubt forum staff is going to be able to do anything beyond possibly banning the IP that was used to intrude into your account (and won't even tell us about it), which would most likely be done through a proxy unless the hacker was a blind idiot. I'd be more concerned if they used it to gain access to your in-game stuff for real.

It not just forum account, its same login for the game
