Elevator Glitching on Zombie warfare server

I would like to report the following players for using elevator glitching on the zombie warfare server:

void sync
opp#Nutella
runner

I dont know if the elevator glitch is allowed, but even if it is its annoying how only 3-4 players know the glitch and others have to wait until the end of the map, even then it doesnt help because they use it in the next map immediately.

They dont kill each other as well.

Ok we will take some actions against them
