Not sure if it's laddered or not. But one guy stood still shooting at a building, I placed like 200 shots from my auto rifle into his head (he was ignoring me, while standing still). So there's no way it was lag, he turned around and killed me then.

But I rarely see any of those cheats at all. I've only seen it happen like 2 twice (armor) and once with the speed. I finally saw the destroying bases with friendly beacons recently as well, which the person was reported and is probably banned (wolf 1 server).
