Saw this article: std's on the internet

"In the past, an individual seeking sex had to hang out at a bar sometimes for hours, seek out individuals, face possible rejection and start the whole process over again. The Internet takes that whole process and condenses it to just a few keystrokes."

One possibility is for state Health Department officials to create online identities themselves, hang out in chat rooms and wait for the sex partners to appear online. The Health Department worker could then ask the sex partner to break off into a private chat room for discussion of the problem.

I know some irc trolls who would be perfect for the job.
