is it illegal to run a Rental business for Blu ray online? I saw quite a couple of people doing this business in low yat? Are they against the copyright law?

So it's illegal to rent blu ray online especially in this forum.
i am certain that most members here are not aware of the infringement and the legality of it. They could end up paying penalties if they are caught red handed especially the enforcer in movie industry . finas don't care much.
