I know "fair use" gets bandied about quite frequently on youtube uploads, but offering full verbatim downloads of any work is highly unlikely to be considered fair use if a court were to rule on it. The only reason such sites are still up is that the rights holders don't care enough to sue.
We need adverse possession ("squatter's rights") for intellectual property.
I'm surprised copyright trolls are not buying IP from defunct game/film/music companies and suing youtubers left and right for uploading video game music and anime OSTs.
If I were a sociopath and didn't care how I make my money, I draft some legit-looking legal threat letter template demanding $10,000 to avoid a civil lawsuit worth millions, fill in the blanks with a name, IP address, and title of pirated content, then mail out the letters by the tens of thousands using USPS-subsidized cheap mail.
If you mail out about 20k of these threats, you only need 3 of them to pay up to come out on top.
