A pretty sad individual if thats what he feels he needs to do to have fun. However i wouldn't be surprised if theres others calling themselves Kim V just to get on youtube
Just report him to Sony. Google how to report players to Sony. I've not been in a race with him but have seen numerous videos of his exploits. PD seem to be doing nothing so best use Sony. At the end of the race see what are the two names he uses and send the video in
