My friend got banned.
Really didn't surprise me at all though. He's had 2 chat mutes the past 2 months and still didn't change his in-game behavior, so now he's sitting at a 14 day ban.
He didn't blame riot because he knew what he was doing. He was calling others trash even after 2 warnings. Let's just hope that after the 14 day ban is lifted he decides to change, but I doubt it.
You know that feeling when you work your ass off for a game and you have a friend/cousin pull the classic five finger discount and you hope to see some justice served. That's the feeling I got whenever I'd see him getting toxic and blaming his teammates and calling them trash feeders, which he himself was guilty of that very thing.
So really what we can draw from this is if you're toxic, it's not a matter on "if" you will get banned, but "when". Some people it takes a few years because they're borderline and others it could be months because they see no reason to change or even care.
