Trolls , are they punished?
So Riot's system of banning works extremely well on negative players when it comes to chat, but I'm confused as to how trolls get banned. When I say trolls I mean players that go afk because you took a cannon minion or buy all boots because they are losing lane, just toxic players that purposely throw games. How does the Riot system ban these people without a tribunal or game reviews or something of the sort? 
running down lane feeding with malp" simply because riot's shitty AI cant tell the difference between a troll and a bad player. especially if a troll is really good at hiding the fact theyre trolling. or use 5 man premades to "play off" report warnings
