it's not only here: the ads are automatically targeted to the keywords on the page. Soon after a site admin block them, they show up again, probably tiggered by different keywords and linked to different sites. However they do it--innocent money ends up in the wrong pockets.
hehe--the advertisers are as quick as filesharers in getting around blocks.
