Would Perma-ban or Season-ban even work?
People who threaten to quit in ranked and then actually leave, would perma-ban solve this problem? The logs are quite clear, if someone threatens to quit and/or griefs and then quits a ranked match (happens all too often) I do believe they should be perma-banned. At least from ranked play on that account, or for the remainder of the season.
It just seems so prevalent and the disciplinary measures so ineffective.
