RFC: system for verifying confessions ownership

Not something that particularly needs to be implemented, just something I was thinking about and might be useful to share.

Rn, theres not really a way to verify that you were the person who sent a particular confession with prox2, which could be a problem when sending multiple confessions on the same topic, or when replying to a thread multiple times.

One way to solve this could be to supplying the confessor with a random value(key) and then when the confession is posted, post the hash of it along with the confession. that way OP can just chain their keys at the end of their messages to prove ownership over that particular set of messages.

I can see how this might not be a very valuable feature for the confessions bot which makes sense, this isn't really a problem I see a lot, but one place where I think it could be useful would be to only supply that hash to the CRT team when the confession is being verified, that way OP has a way of proving that they were the one who posted it if the confession was something like a security disclosure.

The bot would like show the key for 30 seconds then delete so you don't have message history with prox2
