U shouldnt pay attention to him, he acts like that in every match, if you want to report him you can do it by sending the replay with screenshots and a short description of what happened to this mail: enforcement@relic.com . The best thing you can do is just ignore him and dont write in chat, if you dont write he usually stops, i reported him myself but he didnt receive any sanction so i think its kinda pointless
LeLic ~~I dont know how to sending screenshots on ORG (link???) thank for you help. yes I try to keep my eyes on right and dont look what he typed. but this guys really so Annoying.
