My question is pretty straight forward. Why can't I flag a post as duplicate of another post, if the owner of post has accepted one of the answers? I'm asking this as recently I've flagged this question as duplicate of this question. But the flag is declined with the following comments:
declined - If they have accepted answers, don't bother to flag them. It just creates noise.
Please note, I don't have any problem with declination of flag. I just want to know whether this comment is appropriate. If so, I'll take care of this thing while flagging post.
