No, we do not have to state it. It's not allowed because its a fairly random occurrence and unfortunately not a proper way to measure player skill in a competitive setting without promoting reset cancer runs over actual skillful play of the game and working within or around its mechanics.
We have already discussed this in the past. Things like that and the reloading/over-maxing clip glitch were also handled the same way. Tho the Reloading glitch that I'm speaking of was later patched due to how abusive it was. There were other things as well that were then later patched after fair bit of time bu ultimately if we see it or its brought to our attention we will deal with it.
yeah i agree abomination death glitch shouldnt be allowed. why is there something not allowed but absent from the games rules?
