This is part of the anonymous feedback feature for people who don't have the ability to vote, there's a whole tag about it on the parent meta (Can't seem to find a blog post about it):

- http://meta.stackoverflow.com/questions/tagged/post-feedback?sort=active&pagesize=50

As far as I can tell we're collecting the data in the system but don't really use it for anything yet. 

The questions show up for users with 10k reputation in the review section, but right now it just shows you which questions are getting the most anonymous feedback so we can improve/vote on questions which are being voted on by people on the internet who might not have an account or can't vote.

Perhaps as this corpus of information gets larger we can do something with this information but I really only go in there every once in a while to see if there's a page getting a bunch of "this is not useful" links.
