You do understand that the Malware has nothing to do with the website? and by that I mean that it's an adnetwork that controls what adverts that are displayed, and that many many adnetworks have been used to malvertise.
Most companies are not going to want to be associated with TPB, so most ad networks are not going to want to assocaite with TPB. So, the bottom of the barrel, scummiest ad networks are going to be what it would have to use to keep the lights on.
Just my two cents though.
