Ya, that's *stalking* but well, stalking already has a prescription in law.
Naturally the international nature of the internet somewhat limits what you can do, and discovering that people making threats are basically children wouldn't do you any favours either.
Nina had people track down her website and post hate mail on it.
Don't have a website if you don't want racist, biggoted or threatening comments. I'm a game developer and a university professor, and well, students who don't like their grades seem to turn off the filter when e-mailing to a private account.

That's what security is for. There's nothing here about 'women in __________' that's 'if you threaten someone for any reason the police will be called' territory.
The post is essentially cherry picking extreme cases. Ask any woman who has had a stalker if it's a good experience and the answer will be a definitive no. But you're not going to prevent stalking completely through education, no more than you can completely eliminate murder either. 4 hand picked examples of extreme cases is hardly the basis of serious policy discussion on a broad issue.
