DONTPLAYLEAGUE: LOL YOU DUMB KIDS DIDNT WIN LEGIT
DONTPLAYLEAGUE: YOU WON BECAUSE I TROLL
Ok, this one is the worst of all. You've already given up early game just because you had a bad matchup, offering the enemy team to run down mid, called more people names, and also admitted to AFK/trolling.
So conclusion, you should have been permabanned instead of being chat restricted, so you got lucky.
