Any content moderation is censorship. However in large group chats, this might be necessary..

Are you also considering "content moderation" in chats between two people?

Im ok with censorship, as long as I can decide myself who I want as moderator and if I can change/undo it… maybe even using different moderation filters in different views: see https://primal.net/e/note1vz092ce05t5vr5k6wezmv2uk2a2rx6nh3768vkswplxaw7umr37sm6d6cl

> both sender and recipient would have to modify their clients. It's technically complex, so most users won't do it

It would be a wholesale failure of open source if this were the case.

Suggestion: 1) Add a ”Remove” button on all messages that a user can click. 2) Before showing a message, let the app check with users you are trusting to see how many percent of them clicked ”Remove”. 3) Now you have decentralized spam protection. It scales. Moderators cant shadow-ban (if impl correctly).
