I guess they get some sort of high out of the idea that they have destroyed someones hard work in leveling their character. The only online game I ever found to be lots of fun to hack was graal, but thats a mass PK'ing community, so if you become all powerful, no harm done, except to all those pk'ers pride. Didn't matter to me, I maxed out everything (other then money) in the game while playing legit, so I was all powerful anyways. Oh, and for those of you who don't know what graal is, the name Zelda online may ring a bell.
