Do you run your own PeerTube server? Would you like its videos to be listed on the official PeerTube search engine? If so, add your server's domain name on the index page at:
鉃★笍 https://instances.joinpeertube.org/instances/add
The search engine itself is at https://sepiasearch.org and is integrated on many servers.
(By the way, if you see a domain listed on the Sepia Search index that has nasty stuff on it, you can report it by emailing rt+abuse-peertube@framasoft.org )
