If they really want to, they can find you. ISPs (internet service provider), businesses, schools etc. are given a block on IP addresses. In the beginning, you could tell how big a company was by the first 2 portions of the IP, but that no more I think.
With Dial up ISPs, you are typically assigned an IP when you log on, so you'll rarely have the same IP. But the ISP can go through its records and find out what you IP was at a specific session, so things can be traced back to you.
I wasn't concerened about thing being traced, it was just odd that only one thread was being monitored.
