Pixel? Hmm let me think, I know I didn't take a demo.
Right, I remember now, there was a player called Pixel and he started calling names and insulting, directed at me after I warned him he tried to provoke me and I remember well that he said if I ban him I will lose my rights.
At first I tried to give him a time ban 5 min, but that didn't work since he came back and said - YOU CAN'T BAN ME. Well I did it again, he came back and continued with the same attitude. I also said to him if he joins back in the server he will be permanently banned if he doesn't stay away for an hour, which he didn't. I had no other choice as to use amx_permban.
Now, whoever it was, the offense was what it was, if it was your brother, sort him out. I'd say keep banned for 1 week, since we don't accept such excuses (family), you will have to serve your brothers time.
