Interesting. To the best of my knowledge, Discourse does not reveal to a user that their post was deleted, let alone who deleted it (but I’d ask @codinghorror to be sure). In the site I help moderate, we (the mods) participate as regular users, and moderate as needed. It has never caused an issue for us, and part of the reason why (I think) is that we maintain clear rules/guidelines so no one is confused when something happens.
