Wall-glitching
It is strictly prohibited in this server. Wall-glitching is an act on which you 'purposely' use the game's bug or any other unfair way to shoot through a wall to hit another player. This includes bugged or non-solid places/walls that are accessible by foot but covered by texture.
It wasn't even wall, it was glass doors of office from where i pop'ed your head.
