I'd imagine they want to deter people from following in my footsteps, so publicizing their actions serves as a warning.
If anything, I'm encouraged to start a publicly-available database based on crawling Facebook. Don't associate your name with it, crawl from your Ipredator account, and make sure your data is spread far and wide. Then they can sue the Entire Internet like the music companies are having so much success with.
Information wants to be free.
(Also, what's the worst that could happen? You get sued, and Facebook gets a few thousand bucks from your savings account and your used mattress? OH NOES.)
