Yeah well. onlyfans@lemmy.world is already claimed. Though you can create another account on a different instance where it is not created already if you don’t mind the hassle. I also don’t think you need to even know about how fans work just to make a community about images of literal fans. It’s your choice.
I used to use it with RethinkDNS’s custom DNS so I never had those ads people buy ad-free to get rid of (there are still placeholders which kind of annoyed me). The UI is pretty nice, it also has features Jerboa does not have. Such as advanced searching that can search users and comments as well (this is possible in the web version), or mod tools. There are a few others but I still decided to switch back to Jerboa because FOSS.
