Plebbit is a selfhosted, opensource, nonprofit social media protocol, this project was created due to wanting to give control of communication and data back to the people.
Plebbit only hosts text. Images from google and other sites can be linked/embedded in posts. This fixes the issue of hosting any nefarious content.
ENS domain are used to name communities.
Plebbit currently offers different UIs. Old reddit and new reddit, 4chanw, andhave a Blog. Plebbit intend to have an app, internet archive, wiki and twitter and Lemmy. Choice is important. The backend/communities are shared across clients.
The downside is big instances decide which content to show their users. If lemmy.world defederates some instance that's content I would never know existed.
So... sounds like you need a new instance? One that doesn't defederate from all the content banned by another instance.
The point is I don't control what the admins do
Be your own admin. The option is there, and let's you control the admin.
