<strong>PeerTube 1.4</strong> added a plugin system, and made sure plugins can for instance automatically blacklist videos or reject comments based on any rule (similar to Pleroma MRF);
<strong>PeerTube 2.0</strong> setup now asks the admin to answer questions regarding their moderation policy and dedication to it. Make a feature to automatically follow a public index of PeerTubeinstances part of core PeerTube, instead of leaving admins to script it themselves. This allows instance administrators to automatically followinstances of a "follow list" of their choice; a list which is self-hostable, so that communities can grow at their own pace;
