Last Round i played on his Sever and not just me noticed that he is using a wallhack and eventually an aimbot. 3mins after game start he got 27 kills and 2 death .. later in this round he knowed exactly where we was. 4vs 1 and to 90% he won + often he kiled us from behind ( from our spawning side).  u cant chill anywhere for 10 sec. he find u on the hole map.

oh sorry here is the link:

Where's the evidence of wallhack?

oh and i forgot to say one of my teammates watched the twitch stream from:   https://bf4db.com/player/1957814001 
while he played on the same server against him. he said mattiboss is wallhacking 100%

he streamed live while he was hacking -.- thats dumb 

Please provide a clip or highlight of the section he is "walling" in please.

I don't see any evidence. He was actually streaming the game when he was playing but its hard to confirm anything since you havent even provided us with a battlereport. Hes also someone who plays locker only a majority of the time so it would reason that he knows the map well.
