Well as this will probably be my last work on the subject I have to say that the kind of thing you talk about is actually very scary in general. The pack mentality of those people is dangerous and it makes me uncomfortable when they are around. They are just bullies in general and really are what is wrong with it in general.

I still think the best way to deal with them is to ignore them, after all they are only doing things for attention, goes for hoaxers as well. If you take their attention away, yeah they might follow you around and you can't tell others to block them, but at least you don't get effected by it anymore and that is the important thing!
