Maybe I'm missing something here, but someone uploads a film, shares the link, loads of people download it. Referral earned.
If loads of people download it, the entertainment industry can find the link too. Then, they'll know the encrypted content is their movie, and lawsuits start.
by entertainment industry you mean Hollywood? wouldn't they need to download the file first to make sure it is their film? and wouldn't that be illegal and they couldn't use it in court?
