Rejected Challenges

Recently I made a challenge for my course "Castle COMs" to complete it in less than 28 seconds.  The challenge was rejected my moderators, and although I partly understand why (I used an ultra shortcut that skipped part of the track in the last lap to achieve that time), I found myself a little annoyed.  I think that when mods reject a challenge, they should have to leave a comment describing the reason they chose not to publish the challenge. I feel this would definitely help people whose challenges were rejected in terms of understanding, so I think this should be a feature that should be implemented.  Alternatively, it could be nice if the mod that rejected the challenge could just leave a comment on the course itself .

This feature is already avalaible. Moderators can leave messages when they change the challenge's difficulty or when they reject it.
Sometimes, they don't need to leave a comment for obvious reasons (for example, spamming challenges).  I understand that you were a bit annoyed. I don't know who rejected your challenge, but I guess the validator was irritated because it's not the first time we encounter a challenge validated with a super cut.
