Account hasn't been toxic, missed a payment on bills or been warned by leaver buster. (or put in low priority queue for it) Riot only does 2 week/Permanent suspensions for toxicity, year ban codes for billing and not sure about leaver buster. Ban says check my email but there isn't anything in the email?
