It's just cubecraft with their stupid and useless anti-swear filter. I mean come on, you can't put a / or a + in chat without your sentence getting censored. Oh, and by the way, what I just said isn't even allowed. Why? because I said: "you can't put a" and puta is spanish for whore. I mean come on, It's annoying as hell and if someone wants to say puta on cube the can whether some versions are censored or not. Examples on how easy it is to bypass: put4 put@ p[_]ta p(_)t@ P urfdrhi U rhfureghf T frghfire A pu+@ etc. Now of course not all of these examples would work, but you get my point. I can't even put a lenny face in chat? And it's not like censoring some stuff is going to stop bypassing. There will always be a way and it's extremely annoying. I really don't see the point.
(oh and don't forget the struggle when someones IGN is censored and you want to talk to them, yeah)
