it's basically a social score to evaluate the handling of a market rather than the quality of a market. 

A trivial market resolved correctly vs A controversial market handled well get the same score currently. 

It's also quite subjective as you're rating the creator and people may use it to spam low ratings on other users they dont like. A like/dislike counter per market would be better to surface high quality markets to the top.

Edit: If the system is removed and later added back in, this market resolves to YES as the system did indeed get removed.
