Peertube works great. It probably needs better moderation federation same as mastodon (as a mastodon admin you need to download and maintain your own blocklists which is quite tedious).
What we need is the option to automate blocks. If the instances you follow have converging bans, your instance should be able to copy them and that way have bans federate through the system and have trolls and other scum get the boot everywhere.
