We ran in to this with the scuttlebutt apps too. For example Manyverse.se was temporarily banned because they didn’t have a centralized way of reporting and deleting content. There is no way to delete in scuttlebutt but apple was ok with it looking like it was deleted by hiding it.

With planetary we were forced to collect user data and make it so the app called back to a centralized block list. Manyverse solved it by providing no server information at all in the app. Both solutions sucked.

Apple simply doesn’t believe decentralized systems exist.
