Damn, I tried to simulate a leecher by doing a search for US Gold then opening a bunch of pages (about 40!) and it didn't prompt me for anything! I feel let down!
RCK: I'd be interested to see when you popup the leech requester - is it based on a certain number of page requests in a certain amount of time or something? If I closed the window as soon as the page appeared does that circumvent the leeching code or that runs before any of the page is sent?
