Seriously why? Discuss.online has horrible moderation and open-signups, and Lemm.ee isn’t very much better. If lemmy.world and sh.itjust.works were completely nuked to avoid the moderation headache or risks from two large open servers, why aren’t lemm.ee and discuss.online banned as well?
This is probably worth a peek in moderator logs to see if they have an outsized amount of moderation. The two we defederated with happened when Lemmy was first exploding in size and were in direct response to size as well as moderation strategies and open signups policies. We don’t want to cut off our community from folks on these instances but if they’re causing a lot of trouble- we can certainly consider it
If that’s the case and there is a desire to have community reach maybe older defederations should be re-evaluated. But I wasn’t under the impression that it mattered much compared to safety of minority users and security of the instance.
