Im not actualy banned (yet) but i have been faced black screen issue now twise and think its some kind of metod to find bot's. It just turn my whole screen black so i cant see anything but gb still "somehow" know what to do. It can be fixed with command /reload. I dont know are you guys already knowing this and try to find way to avoid it but if u dont i highly recommened to look at it. Its probably method what gm's use when some one report other player using some kind of bot.
