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!
Each user can block other users. Moderators can block users. It can be handled the same way that other sites (yes, like reddit) do it. I’m also not opposed to defederation when it is essentially a single-user ban- for example, if there is an instance with no communities, no signup requirement, and has nothing but malicious bots- that’s banning a bot farm, not “defederation” as it’s commonly understood. But with something like this- where feddit.nl is actually a rather large instance- so many people are essentially being punished for absolutely no fault of their own.
