What if you got a program like xrumer and spammed a few hundred forums with a cookie stuffed image. You could post a topic title like "check out this picture" so it does not look like spam and deleted by mods.
The basic idea is you would get a shitload of clicks, so if they were ebay cookies you could make some serious money as a lot of people buy from ebay and you can target forums that relate to what you are selling.
