(semi-OT: I'm also surprised how those screenshots are paraded around as "aha! caught them!". Did anyone seriously think there wasn't any moderation of trends etc going on before?)
Looks like there's a network of these guys, doing RTs and talking with their group in order to gain followers.
Most of them sell courses and ebooks.
I too am surprised at people who thought the trending list was organic. It's been obvious from the day it appeared that it's curated and/or paid for placements. Purely from a programming point of view, trying to keep hate speech, racism, and shock content out of it automatically would be nigh on impossible (q.v. recent AI attempts to do this sort of thing on News sites and Facebook).
This is pretty similar to conspiracy theorists vs normal people with regards to the US government spying on people before Snowden.
The reason why I liken this to Snowden is because at least anecdotally, the typically dialogue I have seen is
Conspiracy Theorist: "Twitter are shadow-banning people!"
Normal Person A: "That's a dumb conspiracy theory."
Twitter: "We are not shadow-banning people."
Normal Person B: "Here is proof that Twitter shadow-bans people."
Normal Person A: "Well yeah, obviously. It would be pretty naïve to think they weren't always doing this."

You can quite accurately substitute Twitter with the US government, shadow-banning with spying, and Normal Person B with Edward Snowden.

There's evidence of manipluation of threads [0], shadow-banning / blacklisting of users on the 'platform' in light of the admin tool leak [1]
Not only 'Trends' are subject to manipluation artificially, but it now matters more about 'who's tweets' actually do show up on Top or Trending sections; even with similar Likes, hearts and comments. Take this tweet [2] for example which proves that they are 'shadow-banned' on the trends section and still has similar stats like the trending tweet.
I won't be suprised to see the same in Instagram, TikTok or many others these days.
