You need to report him in game and submit a ticket there. This thread will just be closed
If you have concerns about a player in game - whether it be their messages, posts, behavior, or legitimacy of their account - and think they are breaking the Terms of Service (TOS) please report them in game! Posting on the forums is counterproductive and a complete waste of your time and PG’s time.
You can report from chats by clicking their name and pressing the report button that also has the ability to block the player. For messages, you can block the player and screenshot the message to attach in a report. In general, you can file a report by clicking settings (looks like a cog) and pressing “contact us”.
