64. That works if you know who the person is.

If you don't, it doesn't, and there's the rub. That's what I meant by it taking a lot of work to suss out who some anonymous poster is. It can usually be done, unless the persona is that of someone who is very knowledgeable.

But the 4Chan crowd, which is the source of a lot of Internet trolling of the obscene kind, is pretty good at maintaining anonymity. I've never really tried to ID any of those people, because I rarely encounter them.

On the other hand, there are a lot of ugly trolls who are not particularly careful about anonymity. For them, it's a matter of a couple or four hours to figure out who they are. That's because they're not very bright and leave clues all around, wherever they go. It doesn't take long to find out who they are in real life.

Others don't care and don't bother to try very hard. But they don't care, either. The folks at Conservative Cave, for example. They're obvious and known, but don't care.
