actually, they do... and they're much more of a pain in the ass than i am
http://www.google.com/dmca.html
they require you to send them postal mail ;-)
and you'd also expect to see your dmca notice on
chillingeffects.org
speaking of google, try something along these lines if you'd like to find out what sites have torrents of your content:
http://www.google.com/search?hl=en&q=filetype%3Atorrent+debbie+does+dall as
the important portion of that search query is "filetype:torrent" if you've got content out there that google can index, that type of search will turn it up for you...
i hope you guys realise, that even though I work for isohunt and the boss is anti-porn, i'm not a bastard, i'm not trying to steal your shit, hell, i don't even watch porn... i'm honestly on your side in this, and i think that if you go about your business in a professional manner, you can get a lot done as far as reform's concerned... shit, it was the porn industry that made the betamax obsolete... porn that made dvds commonplace and the internet as big as it is today...
so please, don't see me as the enemy, i'm personally trying to help you guys out.
