Yeah moderation is the biggest challenge on Lemmy servers, they ended up making it more challenging for themselves with the decision to never defederate from any instance and lean all the way into the hysteria surrounding defederation. That’s really not a sustainable model for the long term, it increases workload, and drives off portions of the userbase who are sensitive to extreme or aggressive people (the people who run wild if you never defederate troll instances or ban trolls).
