I was reviewing First Posts and I got one that looked like a duplicate of another answer. Here's what it showed me after I failed:

https://superuser.com/review/first-posts/492517

However, when I was presented the post to review, the user information was different. It told me it was a random new user (user#####) with some very low reputation. I am unable to get back to the exact screen it showed me so I can't give you exact information. The answer looked pretty good - because it was - so I went to the actual question to review what other answers existed. The question seemed pretty simple so I expected to find another good answer already posted.

Sure enough, I found the *exact* answer already posted. "Huh," I thought, "some relatively new member has copy / pasted another answer. They must not understand why that's bad." In fact, the answer I was looking at didn't even show up so I guessed it had been posted, deleted, and was now being used to test me.

My plan was to leave a comment in the review panel explaining why it was not a helpful answer and then flag it for moderator intervention. However, as soon as I posted my comment in the review panel, it told me that I failed the test.

I have two questions here:

 1. Did I get trolled by the review process or is it common practice to change the user information and comments to make it look like a new user's post?
 2. Why did I fail as soon as I commented? How is that indicative of me judging it incorrectly? What if my comment was to say it was a fantastic answer and I welcome them to SuperUser? Even if it *is* a bad answer and I'm going to flag it, isn't it better to leave a comment explaining to the new poster so they don't think people are deleting their posts for no reason?
