Lately we have been dealing with a few abusive members from Feddit.nl and we were unable to get in touch with the instance administrator.
Part of the problem is the instance’s open registrations which do not require you to enter an e-mail address during signup. This in combination with an inactive admin is a recipe for abuse.
We hope this is only temporary but we have to do this to protect our users.
Edit: we use fediseer, have a look https://gui.fediseer.com/instances/detail/lemmy.world
Edit 2: We got in touch with the Feddit.nl admin. Email requirements were added to the sign-up process and we’re setting up a communication channel. So that means we are federating with Feddit.nl again!
Nope, in order to not overload lemmy servers, the lemmy software does not federate pre-(re)federation content. That is one reason why I find it a bit ridiculous to wield the biggest stick you have, defederation, so freely.
I think in the case of an instance being spammed with csa material we are allowed to use all the sticks at our disposal - and in this case it was actually the only stick we had. And once we got in touch with TedVDB we refederated.
He’s now also in the chat room where most Lemmy instance admins hang out. I’d say that’s a positive for everyone in the end.
