The rating system is a relatively new function --- and there really aren't that many profiles that have received "votes" or ratings....I think the most I saw was like 10, or something. 10, that's it!!! That's not a lot to rate a single profile, so I would recommend people should start rating!
Over time - the quality profiles will rise to the top based on the rating. It's the law of large numbers and I really think that the best profiles are getting their due. The Mitch Malloy profiles are better than most I have found and they are getting positive reviews. The problem is that you can't sort based on the rating! So you manually have to look at each page and see who has good ratings. This is a bit cumbersome for sure.
When people start actually rating, I think everyone will benefit. People are reading WAY too into this IHMO.
If you don't like the rating system today, don't use it. Simply do what works for you.
But some of the methods and recommendations I have read on here are entirely way too time intensive to gauge whether or not your like a profile. Soon we are going to be around 10,000 profiles. Keeping things SIMPLE is crucial.
