PeerTube is part of several actions assembled by Framasoft in the <a target="_blank" rel="noopener noreferrer" href="https://contributopia.org">Contributopia roadmap</a>.
Indeed, we do not claim to have the science behind it and know how best to manage each of the tools according to each of the needs. For example: with regard to the question of DMCA requests, cases vary according to geographical jurisdictions (European law is different from French law, itself different from Canadian law, itself different from American law, etc.). Concerning the tools for moderating comments, here again, we cannot decree ourselves experts of the subject, because this is simply not the case.
However, on PeerTube each account is linked to one or multiple channels that can be named as the users sees fit. You also have to create at least one channel when creating an account. Once the channels have been created, users can upload videos to each channel to organize their contents (for example, you could have a channel about cooking and another one about biking).
