Firstly, Why do we have this? All it is is a flawed system for cowards to hide behind. The systems bring no good to the assessing standpoint.
All I've even seen it be used for is either people who want to give shit assessments because they don't like one of the authors (Which is not allowed) or people who use their friends to give them high marks and don't wanna be caught doing it. (I know mods can see them somehow but still.)
I REALLY see nothing good that can come from this kind of system. If someone can somehow persuade me into thinking differently go right ahead.
