That "something fishy" add is actually run by google adds, the web site does not really control it, although they can block specific adds from showing up if the owner where to contact google.
When you see that add, click on it and follow a few links on the page (so your hit is registered as a "detailed viewing")....Google charges there advertisers, per hit. and probably more for the detailed hits....hit them where it counts...in the pocket book!!!!
