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?
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.
