1)No hacking. (Ya fucking obviously?)
2)No ego-ing (as in serious ego, if your'e kidding like "ROFL LOLOLOL LUCK, LOL JAJAJA NOOB" then its ok, but make sure he is your friend and will not take things seriously. If he takes things seriously then you better not do it again.
Take me and Kangjun and Seb for example, I know him for 2 years that's why we can ego each other, but seroiusly we're all kidding.)
3)No cheating. S = S. B = B. Insta = Insta, I'm sick and tired of insta then shoot on floor, it's lame.)
4)No inf glitching.
5)No calling others lag-shield, this is SG/MY, even though lag is minimal i agree there are some people who lag shield, but just live with it and have fun. Stop taking things so seriously.
