Yes, it is stupid indeed, but that's licher and it is nothing new from him.
You already know how "Chat Moderation" works, and in this case Licher considered that the word "Fuck" in this case was mute-able and he punished pujo for it. (Even tho in my opinion that is a really stupid mute but hey, its up to him 4Head)
Says someone who tryharded to report a player for saying "gtfo" and "stfu" (And also reported me for saying "fucks" too) http://i0.kym-cdn.com/photos/images/list/001/100/963/ab8.jpg
There's nothing to be discussed here, and even if there was something to discuss, it certainly wouldn't be discussed with you.
Closing the thread due to the 2.15 Rule.
"2.15. Publicly criticizing or discussing a decision made by a Staff Member or their actions."
Licher made his decision, if the player disagree's with it, he can appeal here http://forum.pandawow.ru/showthread.php?t=78845
