In a similar approach of [slhck's problem](http://meta.superuser.com/questions/4515/flagging-posts-that-answer-the-question-with-something-the-op-has-already-dismis) I thought that being very descriptive instead of just clicking *not an answer* would help, but instead I got a new flag reason returned:

I don't feel like the rejection reason makes sense to me, because my flag reason *tells  the exact opposite of that*.
