On my question here Why should I use foreign keys in database?, this user @jaymee has constantly been bugging me. I ignored his first comment. Then he comment on the accepted answer. I replied to him then that I have accepted the answer to my question and he shouldn't be concerned about it but he constantly jumps in and tries to school me.
Even when I tag other user in commeent (in reply to them), the jumps in and tries to lecture, "you are not listing at all", etc etc.
I couldn't find a way to report him on his profile. what are my options and is this behaviour reasonable? You can bug someone once but he is at this question again and again and even downvoted it (which I am fine with).
