I'm reminded of a short Sherlock Holmes story that went along the lines of the police receiving a letter from someone claiming to have an acid that could eat through anything, and they were threatening to use it if they didn't get what they want. Holmes tells the police the person is bluffing and to ignore it. The reasoning being, if this person had an acid that could eat through anything, they would never be able to store it, because it would eat through any container.
In any case, they were doing okay until they said they would turn your CPU up to 2000% and break your computer. That requires physical access to your computer. And so since they made a blunder like that, I would bet that they don't even have a clue what an IP address is or how to hack into a computer.
The downside to our ever increasingly connected world, is that all the crazies who normally were pretty isolated, now have chat rooms, message boards, video games, etc to spread their craziness.
