Well. no one likes to be griefed. I know of one guy that goes around to certain places and crashes peoples graphcs card, this is something he wears. He gets banned and ejected, and yet he comes back with a brand new alt to do it again. I have reported this to LL several times, and I've come to the conclusion that they simply do not care. I've been in SL for 10 years now, and there was a time when they actually did seem to care. Times sure do change.
Yes, land ouweners do have certain tools, but LL needs to make more of an effort, and help us. No one likes to be griefed, and all they can say is that we should ignore them. We cannot ignore someone that crashes our video cards.
