I'm thinking of what moderation rules I would set if I were to set them for some microblogging server. I'd do something sensible and normal like have specific rules that only apply to replies, like: no reaction gifs, no links, no photos, no changing the topic and no evangelising ('have you tried rust/mastodon'). Each top level post is in my mind a new forum with strict rules against off-topic messages or posts that don't contribute anything new.

But more than that I would want replies to be hidden by default. With the original poster being the moderator of this microforum. Maybe able to set the no-links etc rules per post.
