I've seen that on some other forums, and in a limited case at one contest I attended Cave_Dweller. But here I think things are pretty low key, with suggestions/critiques tending to be on the friendly/gentle side. This makes the contest a good place for people to either to try and pull out all the stops on a genre that they are familiar with, or totally try something new.
I think most of the modelers embrace the "goal is completion" type attitude, that Scott and the other staff cultivate. I know it's one of the reasons (aside from the wicked builds we see daily here) that I stay active on this forum and look forward to the contest every year.
