You don’t find people on patreon, you find them on other platforms and then pay money typically for some way to interact with big personalities. I doubt there is much demand for scrolling through an index page of strangers to pay them money.
I know why, look at the front page of bitschute (or however it is spelled). It's full of conspiracy and extremists videos, if only fan showed popular stuff it would be 100% porn.
maybe because most overly puplic communities turn into cesspits?
