I’ve never pirated rentals before, but there was a guy who got busted at my work for the like. It was at the post office and he had been… borrowing(?) mail video rentals, taking them home and making copies. He would return them to the mail stream the next day. I’m not sure how the inspectors caught him, but it was rumored he bragged about having hundreds of shows and movies. He never even had a subscription lol.
