I'm not quite sure what your angle is for this example, TikTok clearly serves low-follower & low-view videos in their algorithm. It's probably about every 1 in 8 videos if you scroll on the FYP. Each video is given a 1000-view chance to see if it gets boosted further.
Depending on what you like is what you're served, so if you like Home DIY videos & follow those accounts - you'll be served that. They then mesh in the more popular videos depending on external likes of people you follow, general trending (probably 1 in every 5 videos), and location.
If people are telling me TikTok serves scam, manipulating content... it's because of the videos they liked & people they follow. I doubt their account is dedicated to looking up SDR radios, fixing electronics, and general DIY videos.
It's incredibly easy to test this. There's a rough 4-week learning curve per account created that fine-tunes the content delivered to the user.
