"Someone with the resources of the NSA or CIA could no doubt trace all of this and find a person."

Half the kids in the computer science class at the local high school could also. It's really not all that difficult. That's why turning on IP logging is such a bad idea (bad, at least, to those who value their personal privacy -- I certainly do).

For anyone who doubts me, visit http://www.slashdot.org and post a challenge for someone to track you down based on your IP address.
