A nasty comment

During the Christmas rush I have not been in sync with my online life but I have been doing the necessary maintanence. This is mostly typical stuff such as making sure spam does not get through. On the 22 December I recieved the nastiest comment ever on this blog.

The comment was to a post on the Fourth Nordic Conference on Scholarly Communication and made nasty, arrogant, vulgar, abusive & sexual comments about one of the persons mentioned. The comment was a nasty type of Cyberstalking and I simply removed it. But I am still wondering what the correct response should be. Removal from the visible side of the blog was an obvious step, but should I be contacting someone? Maybe the victim? Or the police?

The comment was signed but I rather doubt that the name was a real name. The comment came from IP number 63.117.244.62 which according to the ARIN WHOIS Database may narrow the search done a bit. Beyond that there is not much more information.
