Moderation isn't an afterthought, it's a core feature of Pixelfed Groups.
In addition, group admins have fine grained access control over members and other instances and an audit log of all interactions by admins and members.
Mastodon is the best way to keep up with what's happening.
Follow anyone across the fediverse and see it all in chronological order. No algorithms, ads, or clickbait in sight.
