Both host content that are against our content policy and have had issues with users from those sites entering our community crossposting content that violates our content policy. We are discussing defederating other instances as well. There is discussion of lemmit.online being defederated because it pretty much exclusively scrapes reddit content and reposts it, and some content creators have expressed discomfort. If there's other instances that might be worth considering defederating from, just post and it'll be added to the current discussion.
and before anyone brings it up, lemmygrad defederated with us.
This isn't a dictatorship but I ask that you please behave in the comment section and at least try to understand why we are defederating.
IDK if this is a hot take, but personally I think the only reason to defederate should be for content policy.
Otherwise, it should be up to individual users to block communities that they don't want to see.
