The solution to that then is to not pretend like PeerTube is centralized by hijacking the name for your URL. If you're hosting an instance, give it a unique name. If MyCoolVideos.com is a peertube instance with a bunch of child porn, then MyCoolVideos.com is going to get labeled as a bad site, and no one will know or care if the underlying technology is PeerTube.

This is a problem with federated services in general. People always seem to want to register on the "official" instance, when really there is none. I think there should be a solution to help people make the decision, or better yet not force them to make a decision at all. Maybe some OpenID-type login/account system should be used instead of having to make an account on a single instance. Or simply stop trying to market the underlying tech, like Mastodon or PeerTube, since that's not going to make a difference to the end-user and will just confuse them.
