@ Dong U Dead - Those posts seem to fit within the thread's topic as you explained it in your opening post, so they do not require moderator action at this time.
@ Furiousboy - This thread is only for reporting forum issues, as explained in the first post. It cannot be used to report issues in game.
If you reported that player in game at the time of the incident, those reports will have provided Jagex with the evidence they need from their own system to be able to take action. They do not accept player's screenshots, as those are easily manipulated.
