This question already has an answer here:
The following answer hit the low quality post queue: https://stackoverflow.com/a/33472146/2312877
Now the answer is extremely similar to many of the already upvoted answers on the question, most of which are from 2009 - but in addition the linked answer provided no explanation to the code, whereas the upvoted answers did.
The "Recommend Deletion" comments don't really fit, so I don't know if it's valid to recommend deletion, but I wouldn't say the answer "Looks Ok" either.
What should be done (if anything) in cases like this?
The answer has since been removed apparently, but either way I've been bit by the automated audit function before in the LQP queue, so I wanted to try to understand what the outcome of situations like this would be - sure you can downvote the answer as one of the comments on this question stated, but that doesn't really help with the queue.
