Another suggestion which I read, but have not tried, is to use your hosts file. You can define the spammer's URL as a localhost domain. for instance yesterday I had some DNS problems with my internal network. Did a little browsing by IP address and the web site I was looking at worked, but it's pop under failed and a DNS error came back. This means that at least this site refer's to it's add server by URL (and I would suspect most sites do) so if you can trick your box into thinking that the URL is localhost then you (in theory) won't see the popus.
