I also get to watch ordinary people surf when I'm doing computer consulting.
Most of these people are Mac uses so they don't even know about having their home pages changed or spyware issues, but they do really believe that just going to a porn site will result in them getting your e-mail resulting in all kinds of spam. Most of them are now using a browser with popup blocker so they don't seem to care about popups no more.
They pretty much blame all their spam on visits to adult site.
