Lemmy world is probably owned by a corporation.
No. It is owned by a nonprofit set up for the purpose. The person that started it brought on a few volunteers (like me) to help out. We depend on donations, and receive some recurring and one-off donations. Every few months or so, we post a short request for more donations as the donations dip below the monthly costs, and that seems to keep us going.
I’m not sure exactly what you mean by “curates” / “shadowbans”, so I won’t directly comment on that. But a large part of the reason I was brought on was to have another person looking out for spam and such.

Well, okay, you can make up whatever you want to believe, I guess.
