I wasn't aware of that, but it's charming to think of Pornhub deleting videos for being "Insufficiently Pornographic", and then for the uploader to argue that anything can be pornographic to someone. Eventually culminating in a court case based on the "I know it when I don't see it" principle.
the meme has been to add pornographic industry titles to benign non sexual videos. that part is just for fun and views
