In an “unlisted” topic:
- If a post is hidden by flagging and then edited, not only is the post unhidden, but the “unlisted” status is removed from the topic. This occurs even when the edited post was not the first post, and no matter whether the edited post was made by the OP or not.
- If a post is flagged, and the flag disagreed with, the “unlisted” status is removed from the topic. It makes no difference whether or not the post was first hidden, nor does the post need to be by the OP.
