I slipped off TL3 and saw that as an opportunity to spend less time on the board.
Even though some posts (like @AndreStmaur’s) disappear far faster than they ought to, suggesting that there are some flag-happy people, it wouldn’t be an issue if it was easier to unflag them. Once or twice in the past I have messaged the moderators to suggest that someone had posted in good faith and shouldn’t have been flagged, but it would be nice if there was some kind of unflag button, even if only available at higher trust levels. (Or, maybe some number of “likes” from higher TL could play that role.)
