They are on your list (which is seen as the official one by many and has most visits) to guide transphobes and fascists to their fitting community?? Exploding-heads is not labeled as transphobe and fascist on join-lemmy. So that does’t make sense.

Yes, I think it would be best if they would all gather on one instance that can get defederated. Right now they attract users on join-lemmy with “Use humor and facts to hold the ruling class accountable”, no other info.

Right now, instances with transphobic and racist content like exploding-heads are still listed on join-lemmy.org. Are you planning to implement a Server Convenant like on joinmastodon.org? To be listed on joinmastodon.org, an instance needs “Active moderation against racism, sexism, homophobia and transphobia”.
