Today in the low-quality review queue, I saw an answer which may, or may not, have been spam:
I was uncertain, but given the tone of the answer, and that the poster had only just joined Stack Overflow an hour ago, and that the linked post did not seem to be directly related, I decided to flag it as spam.
The flag was declined.
My question is: What is the best approach on borderline cases for answers such as this?
