Indeed, but I’d suggest that the “post flagged message” was changed from:
" Your post was flagged as inappropriate: the community feels it is offensive, abusive, or a violation of our community guidelines."
to:
“Your post was flagged as inappropriate: someone in the community feels it is offensive, abusive, or a violation of our community guidelines.”
Whether flagged posts should be hidden immediately and then restored later by moderators or not immediately hidden is a question for the moderators - I suspect that the workload could be quite high if it becomes a well-known “attack vector”. I believe that most other bits of OSM (diary, comments, etc) don’t hide immediately.
