Someone informed me over my TS3 that this guy cheats. I joined the server as spectator (Only admins are informed of spec joins) and the player knew that I was spectating them. "So H3dius welcome on spectating me". He wrote that as soon as I started to spec him.

The attached screenshot shows the chatlog of the server.

Furthermore, he spammed !voteban really often. According to the BF4DB Discord, this is a feature of a cheat.
