Let's say I see an answer that should not have been one and I flag it as Not An Answer (NAA). On this site I have plenty of reputation and am able to use the Low Quality (LQ) review queue and cast delete recommendation votes.
Of course raising such a flag on a still virgin post brings it to the LQ review queue, but what happens if I flag a post on the main site that is already in the respective review queue?
Is my flag simply useless in that case? I doubt it would be the same as casting a delete (recommendation) vote from the queue. And when I somehow manage to find that specific post in the review queue later, it's locked down for me, because I have already cast a flag. So was that flag without any effect?
Based on how I currently guess the system works, I proposed two alternative solutions to improve the system in my feature request here. They were first part of this question, but I decided to split the question from the feature requests.
