I've been working through the flag queue recently and noticed a decent number of Not an Answer flags on answers given a few years ago by users who now have high reputation (>3k let's say). These are obvious non-answers (not specifically picking on this one), but it still feels like cheap flag weight to add my flag onto the existing one. I'd rather not lump punitive measures against a productive member for really old answers.
I would like them cleaned up, but in a manner that is respectful of their earned reputation. Would it be better to add a comment to their non-answer suggesting it be self deleted?
