So recently a forum troll had been banned for posting messages on my wall even after I asked him to stop. He sent me an apology and I reported him for yet again disobeying my "no contact" request. So now he keeps making duplicate accounts on this forum and sending me insults in my private messages. He also posts a modified ( grotesque ) image of me on my wall and around the forum as well. It's been about a week of this fellow doing this. Can I have him sued?
