Been looking back at Graf’s hatred of NOSTR, he accuses it of being full of CP (lie) because its impossible for NOSTR to prevent CSAM from being uploaded by its hosting model (lie).
NOSTR’s media is the least centralized part of it, it’s just a handful of big providers. If your contention is CP, you can just block media from whichever of the media hosts isn’t moderating it.
But lying about CSAM is always Graf’s move, so this isn’t very surprising. A better excuse to get rid of it is text spam. That actually is unmanageable by design.
