I definitely do not wish to see a push towards content that is created for the purposes of trying to monetize or self promote for the purposes of making money. The shilling is the worst part of lot of plarforms because of corporate interests that need to recoup costs or want to have a successful IPO so leads to inevitable ways to monetize users and monetizing users.
Leave the popular crowd drawing shills on the corporate platforms. While it would be nice for the fediverse to have more niche thriving communities if it means becoming filled with shills then at that point why even bother with the fediverse.
If there’s a more active community it could be a good idea to have the community locked but have a thread redirecting visitors to the other community to help the one that’s still alive grow.
