Why do we even have the ratings system?

I just noticed how different the advice the moderators have been giving me on the new ratings system...
In response to me asking why the old feedback system was taken away (I asked because I found the feedback section far more useful than the ratings in people\'s profiles):
[quote=\"lancehoch\"]It was taking too many man-hours to moderate the old feedback system. One mod was spending 20 hours per week moderating feedback disputes, instead of moderating the visible parts of the site.[/quote]
What I get when I report someone for ratings abuse:
[quote=\"king achilles\"]This can be unfair for you if you do not really deserve it however, we no longer moderate the new ratings system.[/quote]
So, the old system was taken away because it took too long to moderate, and the new system is not moderated at all, so why in the world did we need a new system? Couldn\'t you have just stopped moderating the old one?
