Please make sure you are not opening yourself up to liability for not enforcing the TOS (even though you literally can't enforce it). Apple has deep pockets and an army of lawyers. (Android user; I have not read your TOS)

If Kanye makes comment about Jews on Nostr -- either of the two of the following will happen.
-- the clients will be forced to censor that content
-- the clients will be delisted from app store
-- further litigation from ADL and other institutions onto the developer
Saying that the technology doesn't allow for censorship is not a valid reason. By accepting the apple TOS, you are agreeing there are such provisions in the app if necessary.
I feel like apple only goes after those that “copy” them, after they copied someone else if that makes any sense. They’re going to pretend to see nothing because they know no one would use the App Store.
