Every so now and again I see an "answer" from the Formatting Sandbox on the Low Quality review queue, presumably automatically added there due to the number of downvotes it received.
However, the Formatting Sandbox is there just for people to experiment with formatting, so I wonder what those downvotes mean. They don't mean the answer is wrong, like in regular main site posts, and they don't mean disagreement like in regular meta posts. Assuming these answers aren't spam-links or abusive, how should we treat them? Alternatively, should we just exclude those posts from that review queue?
