I just looked at this question on the edit review queue and saw that it was a pointless minor edit to a very old question and rejected as too minor. However, in the meantime, the robo-reviewers had approved it.
Ok, I went to the question and rolled back but it seems to me that the original editor was proposing a minor edit solely for the +2 rep. It will take him a long time to progress like that, but what is the correct action when I see this sort of thing happening? How can I comment to the approving reviewers or highlight the bad edit to the editor?
