I read once where someone 'messed' with a person that deals with the DNS servers. That was shall we say a "bad idea". He sort of had problems getting his internet to work.
It sort of come first hand too. I think he learned his lesson. I can't remember where I read that though. It was a good while back.
It was sort of funny though. Sort of puts things in perspective.
I just wish their keyboards would catch on fire and give their fingers a good cooking. Sort of slow them down a bit if they have to poke at the keyboard instead of type on it.
