One of the different incentives is to shape the mind of people against the will of the parents.

It's quite terrifying that the people in control of children's minds would be the ones who get into such a trade to do that. That's exactly the kind of person you don't want in control of that. Just like people who want to be moderators are the ones you don't want to be moderators. The only good moderators that I've managed to find, are the people who weren't interested and I had to ask them to do it.

That's why you see these authoritarian moderators on basically ever website, most of whom do it for absolutely zero pay, because the thrill of controlling the narrative is reward in and of itself.

That, and probably combatng the boredom of people who do nothing productive in their lives. Also give you more time to do that. People with a job and a life don't go out of their way to do as much modding as possible.
