You presume incorrectly my friend. I have never played in any zombie mods or zombie maps or whatever "friendly zombies" specifically applies to, so I didn't know what that was at the time. Using context clues, yes I could extrapolate what that means and translate that over to normal counter strike, but since it was explicitly listed, I assumed, incorrectly, that the rule about friendly zombies was specific to zombie mods. Bison has however explained that to me after the ban.

As for you not knowing if the banning admin issued a warning... he/she did not. If he/she did, I would have complied with the request. I have absolutely no reason to lie about this and if you do not believe me, simply check the logs.
