It's like IDOC hunting or anything else. People get bored and do something else. For those kinds of griefers, they are so bored and end up getting so indoctrinated into the whole "cheating" thing, that they become mindless zealots. There's a few over at Stratics who dedicate their present UO lives to harass scripters (even though they are also breaking the TOS). Frankly, I'll take a scripter anyday over those who try and cause grief to others.
I used to try and reason with the Stratics folk, but it didn't take me very long to realize those types of people are devoid of any kind of independent thought and must follow in lock-step with the rest of the drones.
