What is wrong with Platinum Elo?!

Since I got into Platinum this season all I am seeing is people being racist, swearing, cursing, intentionally feeding, wasting flash/teleport because person has giving up. This is happening pre-game, in-game and after game. I cannot stand playing in this Divison at all. I had more fun in Silver where people were actually playing the game. I'm constantly finding myself muting people in 80% of my games, that's a high ratio. Time to take action and just get rid of that darn chat box and just let people use pings, least the game will be quiet. Honestly don't know what to do anymore, I've had it.
