I never actually got to play it personally, but I heard Shadowbane used to be a stuffhole when it was around.
Apparently if you tried to turn on the sound the game would freeze and crash right after blowing out your speakers.
It was also infested with exploits and hackers. From what I remember, someone managed to teleport all the major cities into the ocean at one point, made town guards hostile to everyone, removed everyone's gear, reset people's accounts, etc.
