We all need to accept the fact that Riot is just a Company, TBH they don't give a **** about whats going on. Whole Tribunal is just PR move. All they care about is money and things like Tribunal etc are just ways to get more ppl in game which mean more money. For players playing this game for long time permaban just mean, ehm ok I got banned, lets level up a new account ( with XP boost of course) = moneyyyy.
We know smurfing is a problem and we're brainstorming ways to tackle it. But for now, banning the players is better than not banning the players because every time we ban, a percentage of them never come back and that's what we want.
