The recommendation algorithm should distinguish between viewers who happen upon a video like this once in a while and viewers who binge-watch them, and disregard the latter when putting together input for the algorithm that determines what shows up in people's "Watch Next" sidebars.

They could also detect links to compromising timestamps in the comments, take them down, and shut down the accounts that post them. It's not particularly challenging.
