the corps that run the services outsource the job of sending out notices, the companies they pay to do it will flag anything and everything that even hints at piracy. they just have to justify their paycheck.

im just speculating but it would make sense to me if a lot of these piracy troll agencies get paid based on how many notices get complied with and a lot of places are just going to comply without any pushback, even if there is pushback for false flags its not like there are legal consequences for wrong ones so they just flag everything they find and see what sticks.
