1) Wallhacker, first demo proved enough of her but she was still unbanned.
2) Clearly cheating since even when he's alive she still wallhacks, ghosting or not it's irrelevant and you can still ghost and WH since it takes two and if they were ghosting for each other its a two way thing so no reason why it can't be WH also.
3) Ghosting + wh'ing should have the same punishment, telling someone where the enemies are is basically the same as having wallhack.
4) Have fun being permanently banned without the chance for unban this time diabolical cheater.
