I've made three "not an answer" (NAA) flags recently, which have all been declined as "a moderator reviewed your flag, but found no evidence to support it". Why are these flags being declined?
I've read ire_and_curses' post on NAA and I still believe that two out of these three flags were correct.
This answer on deck randomizers in Dominion says "don't use deck randomizers, use this website instead". While that might have been an acceptable answer to "How do I use deck randomizers?", the actual question was "Why are there Curse, Copper, Silver, Gold, and victory point cards in the randomizer deck?". I therefore flagged it as NAA because it does not attempt to answer the question.
This "answer" on shooting the moon in hearts is a response to a comment, and is clearly a comment, but could not be posted as a comment because the user didn't have enough reputation. The question is about the probability of shooting the moon, not asking for stories about people doing it!
This answer on the longest road in Settlers of Catan is clearly by someone who misunderstood (i.e. didn't read) the question. Following ire_and_curses' meta post, I now (just about) understand why this one should be downvoted rather than NAA.
