Ask HN: How do you handle rude/aggressive recruiters?

http://pastebin.com/n3cGvi4E

I haven't received a truly aggressive recruiter response in some time, so it prompted me to wonder how other people handle these sorts of approaches. I'm mostly interested in limiting the harm they'll do to anyone else in their search, as this sort of dialog doesn't bother me too much.

How have you all handled this effectively in the past?

Thanks!
