I failed this auditthis audit, and I'm not sure why. I hit "no action needed" because it seemed like a fine answer, but I was told that I failed the audit. I wasn't able to copy the exact reason why I failed, but I remember it saying that I should have upvoted the answer. I didn't have enough knowledge on the subject to decide whether it deserved an upvote or not, so what should I do in this situation in the future?
