Yeah those bad comments are bad hopefully we will never see them or they get removed. But don't people think it's a little strange to be validating this to each other in a closed circle. This sort of exercise has a few problems including leading people to make fake bad comments. In order to validate themselves in the circle of peers and have others reinforce their feelings. Especially when they can't find these bad comments. Good people don't need others to consistently agree and say they are good.
Personally i work on an individual bases and just call out bad comments if and when i see them. I don't feel the need normally to state "bad comments are bad" and give positive reinforcement to others on bad comments that are yet to be posted or even seen. This is just plain strange to me like walking in a room full of people wearing tin foil hats and being told only the "good side" wears them.
(On a side note i'm more of a lurker and most likely part of silent side that just pays for entertainment and just felt the need to finally say something. I signed up to site at the start because it gave me good entertainment.)
