Valid point – but then you have to account for the lag effect of reversing the mod’s decisions or getting them removed from their position.
Its a discussion I think that is warranted. I’m in favor of a “upvote/downvote” system since I feel it helps give a sense of community when you are contributing to a thread – you feel bolstered by upvotes and want to continue posting. It also serves a function in moderation since it doesn’t tax a moderator to go through every post to figure out which ones to ban/delete – also leaves out the subjective decisions of one person and leaves it in the hands of the community as a whole.
