If you have your name all over the place, I guess that it bound to happen eventually. Curl is used by millions of people which makes Daniel Stenberg kind of a celebrity. With so many users, there have to be some crazies like the "I will slaughter you" guy.

It must be a common occurrence among famous software people, I wonder how they deal with that. Do they actively hide their real identity, for example by using a proxy for licensing, do they just ignore such madness, is it a burden or on the opposite, they enjoy their fame?
