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.
What are the current limits for image updoad (dimensions / file size). Are they being downscaled / turned into jpegs?
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”.
Why don’t you go mope in the corner if the ducks don’t want to get stuffed?
