Hey this is really good.
Also the fake timestamp Kabuki show. If a dedicated actor really wants to correlate by time they can. (Given how relay clumping is still the norm, with time-correlation alone a dedicated actor can recreate the metadata of NIP04 for targeted sets of messages).
Also the fact that NIP17 groups (so-called) are just as susceptible to distribution manipulation as multi-recipient emails in the early days. I could answer "Yes" and "No" in a group at the same time, half the recipients would think I answered Yes to everyone, and the other half would think I answered No to everyone. It is simply impossible to trust that anything sent to you was sent in the same form to others in the group.
