This answer appeared in the Low Quality Posts review queue because of it's "length and content", according to the description of the queue. Since the answer was quite long, I assume that length wasn't the factor. I understand that the heuristic may not be public, but can anyone shed some light on this?
Was this a consequence of the migration, the rapid accumulation of downvotes, or some key phrase in the answer? I presume it wasn't a review audit.
Quality related flags heavily influence this, and the post had one quality related flag which was deemed helpful by a moderator, and the collection of down votes. While we do run quality metrics on questions and answers, we normally don't raise automatic concern unless a post is excessively long, or too short.
That wasn't an audit, but could very well become one in the future - the quality related signal is what we use to find those, and why mods are so particular when it comes to validating them.
