I think we more need to get people to realize that opinions from the internet (and networks) are just in general not legitamate enough and they need to talk with actual people who are around them and not take on ideas they see but actually take in the world and think about what they actually want the world to be.

the only way is moderation and paywalls

A number of the the troll farms and ai bot farms are paid work. Cut out of pay, and the employees will do other things.

How does one do that? Take out the sources of money, of which there are likely a few.

While not immune, moving to FOSS, federated social media helps by removing the profit motive.

Oh, the level of bots on Youtube is atrocious, I wouldn’t even bother trying to fight it, you’re going to lose.
