Are relays already using AI to reject grave content like cp, threats of violence, etc?

Would be nice to see an official badge/certification for relays that do so users like myself can steer clear of dark content. Seems important for #Nostr to go mainstream.

Furthermore, I would happily use an AI filter on the client side to filter out hyper sexual content and even auto ignore users that match a certain criteria.

AI should in theory give us the tools to remove/reject/hide content without reducing user sovereignty or creating a class of moderator gods.
