Some of the tech guru's can probably explain this better (or probably prove my thinking wrong) but it's my understanding that unless Wayne is polling our systems, it's not coming from this 'site'. If it is a hacker, they are probably probing your ISP and thus the node to which you are connected. I don't get any more hits on this site than I do on any others.
It may be something as simple as the sites you visited prior to stopping here, to see if you are still at their site. Of course some of it is hackers looking for a vunerable system.
Sometimes I get ZoneAlarm messages just by dialing up my ISP, without my browser, email handler, FTP program, or anything else being open. Seems like most of the attemps on my machine come from China and certain times of day have much more activity than others. Just dial-up your ISP and let it sit for a while, see how many 'hits' you get before you ever start to surf.
P.S. After reading the other posts I checked my ZoneAlarm, I'm still running v2.1.44, guess that's why I not getting the number of pop-ups as the rest of y'all.
