Look guys, I already locked a similar topic to this and I do not want to put any action towards this. At least not the rule wise. The only thing I do see is at fault is administrators do not issue proper warnings and not paying attention to the chat. See as some have said, swearing is allowed, light swearing. I have asked administrators to stop any heavy, excessive swearing and stop immediately those who insult. Now, the problem isn't the rule, the problem lies as Replica stated in his post and somewhat I see administrators are lacking to control that.
I don't mind swearing, I mean we have allowed it, for a good reason. which is to relax the JB rules and have fun mode with good mood inside it.
I noticed someone saying "A CT issues a warning, if you swear you get killed" - It's not a rule, but on that day, he isn't freekilling if he has issued that warning which again isn't a bad thing. You don't want to be killed? -don't swear simple.
I can switch from having a good time and swear a bit to being completely out of swear words, same as most of us. So as I said, We don't tolerate insulting and excessive swearing at all.
