After this week's unfortunate misunderstanding regarding whose image was actually being critiqued (and as it means different things to different people) is there any way of allowing members to Accept or Reject critique comments on their images?
I realise you can delete existing comments already, but they may have already been read by others - this way comments would be hidden until you click the "Publish this Comment" much in the same way that comments posted to your timeline on FB have to be approved before they go public (if you select that option).
Also this way, Constructive Critique could be a default-on option rather Opt-In as it is presently.
