If an account looks empty:
1. click open in browser
2. select video
3. Copy url e.g.
https://tube.kockatoo.org/w/bxK3vvCfADkqqieww3TSF4
4. copy it to the search field of your app and use it to search for posts.
At the latest now, your home instance / your server knows the first video.
Works also with the nearly 200k Pixelfed accounts:

With @newpipe you can also subscribe to PeerTube channels as well as YouTube. But be careful:
@mycelium @josh @FediFollows @newpipe cool, so, after finding a gem like https://peertube.tv/w/4QTcvrDrQFi44XrkZyUaLi a local search made the video show up in the account view of @thenerdyneko on indieweb.social because a member, me, made the server aware of it. Nice. 👍
