@peertube for iOS, have you considered restricting instances on your "explore" tab to local-only view for the whitelisted servers and allowing us to add servers like on android?
I ask because I was able to land on a server that has "naked news" on their "featured" tab through a video on a whitelisted platform, which might explain why the app stores keep pushing back against you guys. Practically zero reviewers will know how to find objectionable content if they have to know a server address.
