No punishment for sore winner ?

Is there actual punishment for sore winners ? Those players who type ez after winning and proceed to insult the losing team (and most of the time its the 0/5 player who got carried who act like this). Cause i see a lot of sore loser getting punished but i never saw someone post something about how he was gloating just to get punished right after I remember that when Riot Lyte was here you could be punished for typing stuff like "ggez" but is it still a thing ?
