The problem with TikTok is that it's even more opaque than Facebook.
Content can be said to exist or not exist on Facebook, and that's usually it. Sure they monkey with the feed, but it's still essentially user-derived.
TikTok effectively exposes one interaction: get next.
What that returns is completely at the mercy of whatever TikTok decides it should be. They've optimized for virality. But it would be pretty easy to tweak that and optimize for something else.
