Obey The Summoner's Code

I actually took the time when I started playing League to read the Summoner's code, and if you follow it, you'll have more fun playing the game. Doesn't mean you'll win, but the experience will be more enjoyable.

If you have a problem with someone, don't publicize or suggest they be reported. If they make a counter report, you're more likely to have your account banned when Tribunal reviews chat history.
