I like !tenforward@lemmy.world and the newly created !lotrmemes@lemmy.dbzer0.com, both often feature OC - not exclusively but being kinda known for a preference and offering of such. Maybe !starwarsmemes@lemmy.world too, but it’s far less active.

But if people want to offer content, they will. Except often the environment is not welcoming, so it’s a bit of a cache-22 needing solid moderation first, but needing solid content even first-er, which leads to super power mods who know how having to do most of the mod work.

It’s not easy, but we do seem to be growing, even as it looks like from the count of actual people we’re probably shrinking just a tiny bit, though those here are more active. Mostly in comments rather than posts.
