I'd rather have 1 Inter banned than 100 toxic chatters
Who cares if there's a guy talking shit in chat, mute buttons exist for a reason. Riot spends most of their time when it comes to punishing people looking at chat logs instead of paying attention to the inters in game. Some dude saying mean words in chat won't affect anything unless you let it get to you, just grow thicker skin. However whenever someone ints/afks there's absolutely nothing you can do. You know what? At least the person who's constantly throwing insults and spam pinging is actually playing the game.
