That explains the viewer's side, but what about the publisher/influencer side? How does TikTok decide one video is more suitable than another?

My guess is every single video is marked by a human for how much exposure it should get, and if they let something get out that shouldn't, that person is reprimanded.

… Wait what? Why would that be your guess? How is this easier than, you know, anything else?

Just show it to a handful of people, if they liked it show it to more. Keep looping this and good videos go viral, and bad videos don't.

(Essentially using a standard strategy for multi-armed bandit.)
