I was drawn to this LQ review queue
where 7 reviewers chose the option "close", while 3 others chose "looks ok". The post is not closed though: if I understand correctly, 3 of the 7 reviews who chose the "close" option has reps 2k-3k and thus cannot cast a close vote.
This makes me wonder, what is the effect of "close" chose by those users? It seems that it never settle the review: does it raise an automatic flag for the moderators to review, as in the case for "recommend deletion"?
