I have a 5k reputation and so what are the cases where I should use flag because I have some of my flags declined.
Secondly, there are some answers where the questioner didn't accept my answer in spite of commenting and asking whether he/she has any difficulties in understanding the question or not. Is there any way to get the acceptance there. When I was younger in math stack I faced the same issue and out of anger, I downvoted the question. What happened that he downvoted my answer too. Now being experienced I don't encourage doing this kind of silly things. Still, I am in search of a way. Should I raise a flag in these cases?
