My friend was unjustly banned.

My friends name is OOF GOD, we were playing about a week and a half ago. And he was told to take down a KOS sign that was too big. He took it down and then got banned for three weeks. He got banned for nitrp. Why this is such a big deal is because, my computer sucks it doesn't work very well, and NoCancer RP is the only server me and him can play on. So i got super bummed because he got banned for nothing. And second now we cant for for a little while and it sucks.
