He could have easily tried it on himself in his clan chat. No reason to assume he took out a lot of people with him. :? Still it's making use of a bug. I wouldn't punish it.. but Jagex will have a lot to investigate, and it's simply best to not get involved. I'd say don't try, stay out of it. Best piece of advice in this thread. I really don't think Jagex are going to care if you were just trying it, this is one hell of a bug. I do think that doing it at ge and such which wouldn't cause anyone to lose anything is funny (personally) but doing it in pvp/bh is seriously wrong and these people should definitely be banned.
