There's two types of sites:

1) Portals/search engines which just link to the content. These claim they are not doing anything illegal because they are not hosting anything illegal.

2) Video sites that host the illegal content. These sites do take down the illegal content when they find it or receive a takedown request. The illegal content is uploaded in so many places that it doesn't matter if a few are taken down. The sites in 1) point to about 20 sites for every TV episode/movie
