They couldn't sue you period. If all you are doing is posting glitches, they have no recourse, that is not illegal. They made a game and they made the glitches. Now when you sign up to play on line you agree in the user agreement not o use them, but that is diffrent from publishing. Don't sweat it. Even if they tried it would get them nowhere, you would take down the site and they would have no further case in this instance. Trust me I ran a VERY shady internet business to get through college and never got busted.
