As in, AGB’s hands-off moderation, “use the upvote and downvote system to curate content, don’t bother the mods” principle. I don’t like the extreme censorship in the main LGBT subreddits but AGB became extremely low quality when banned sub refugees arrived and the mods continued to use this approach. I’m assuming the admin here is going to promote this instance and make this community active at some point.
I think you’re misunderstanding what the fediverse is. The “fediverse” refers to the technology that allows the different instances to communicate. It doesn’t specifically refer to Twitter clones or Reddit clones, since there are Facebook, Youtube and Instagram clones on the fediverse as well. You can actually use the Lemmy website to view Mastodon posts and vice versa. People have posted to Lemmy from Mastodon accounts and you can paste a Lemmy comment’s URL into Mastodon to view and reply to it like a tweet. The technology behind Mastodon, Lemmy and the other clones is the same, they can all communicate with each other.
