(Not OP.) I can understand that it feels like a punishment though, if you are legitimately trying to help and this is the thanks you get. It's not just a human-to-human notice, but a change of your permission level; you're being stepped down. Of course I have no idea about this specific case and what the user flagged/vouched, and I can see your logic, just that I'd probably also feel bad if it happened to me and the wording seems fitting enough to me
