Usually when I get a declined flag I can look at it and say, "OK, that makes sense." This one I don't get. It was in the 10k tools and had one "not an answer" flag on it. I agreed with it and flagged it the same.
The decline reason was:
declined - a moderator reviewed your flag, but found no evidence to support it
It doesn't answer the OP's question and the author even says it's not a real answer. He's just asking "Why?", which would be a good comment.
- Does marking an answer community wiki remove the responsibility the follow the guidelines?
- Is it some sort of historically significant "don't touch me" answer?
- Is it because it made a good point and was funny?
None of these make much sense.
