Create your own upload site, and about 1000 accounts behind an anon screen. Then upload to your own site via these accounts, as well as opening it up to other account holders to submit links. Follow all of the DMCA guidelines including a removal link. If you host via another site, link to theirs, if not, follow through on your own. If a link gets removed via DMCA compliance, just fire up another account and reupload. Get it to the point through UPLOAD promotion that the only thing you do is insert ads. Download a BU regularly and host elsewhere, using a 301 redirect for a quick switch out in case of banning. If you need a good host, the go with TPB's host (forget the name, slightly pricey, but very DGAF (dont give a F) in the copyright arena.
When all is said and done, you have the framework for a legit social site, and the whole DMCA is just an unneeded risk in the end.
Your other option is a install codec site, with no actual vids involved.
