The asshat that complained on Lemmy.world about this community also apparently messaged the Lemmy.ee admins trying to get it defederated. Just a heads up.
sdf has a few instances, they might be more resilient. I'm hesitant about the ones spun up by some random person who says they'll keep it going forever, but at the end of the day I'm not too worried about switching instances when I need to.
There are a few good ones, I am on feddit.rocks now but it's still in a rather WIP stage (E.g. the defederation policy isn't written yet) so idk if I would recommend that to others, still a nice place without much drama or users and hosted by Kavin (the creator of Piped and long time hoster of multiple third party frontends like Nitter and Bibliogram)
I never used Twitter much so I don't really have a need for it most of the time but it's nice to have a dain option if I do want to look at something on the Bird site! It's definitely great but in this context I only mentioned it because it's part of Kavins record of properly hosting stuff for years.
Oof, I think the easiest way to contact Kavin is Mastodon or EMail but I asked him to create a community for stuff like that on Lemmy. Good luck singing up!
