are you a moderator?
Tennis Expert, from out of the blue, writes an accusatory post on my talk page. I did not contact him. I wrote an equally antagonistic remark on his page and erased his remarks from my own page. I thought it was over. He again posts things on my page and I do the same. If you feel the urge to write a warning on my page that is fine and dandy, but you should also write the same warning on his page because I asked him to leave me alone.
