You may notice in some sites that the sidebar ads are linked (however tenuously) to the subject. There is no human intervention in this- the site owner sells ad space, and a ‘bot’ picks out keywords and drops an ‘appropriate’ ad in. However, the ebay one seems to have excelled itself
I would- but frankly I’m not sure where I would put that many tanks! (Les’s site StupidEvilBastard.com is a master at these- he posts a rant at religeon, and in the sidebar is a link inviting you to be ‘saved’!)
Any other inappropriate ads you’ve seen?
