All Matches
Be respectful and patient with other players. Saying GGs [Good Games] (even if they weren't) goes a long way.
Saying Ggs is the equivalent of just shaking hands after the match in e.g. tennis, and should be done even if you're salty and mad after getting beaten. It is our way of showing sportsmanship and appreciating another person took the time to play the game with us.
Never call people out in main chat, no matter how salty or "annoying" they are/their playstyle is. (This is against site rules). Downvote their behavior for things that are annoying (excessive complaining, rudeness) and report if they are breaking rules by being violent/threatening, harassing, or excessively rude.
If you're dealing with a user that is harassing you, please report them immediately and provide proof.
In Ranked Matches
ALWAYS report your match result correctly. Failure to do so can result in a judgement against you.
If there was a desync or error, attempt to communicate what is happening with your opponent and if you cannot settle on a resolution, please provide proof while disputing the match so that a moderator can review the match. Failure to do so may result in the match being judged against you.
