Please don't post the hack site url anywhere within these forums. It puts others at risk.
Sorry you got hacked but that was NOT a pm message from Jagex staff. They are fake staff out to hack you.
I suggest you make a New thread in the Account Help section and you will get the help and advice needed to make sure your System and Account are safe and secure.
@ cooke fletch - I do not see the accusations that you mentioned in that particular thread. Also, please remember that if you want that user to stay off your threads, you should be staying off of his as well.
