Post game chat should be monitored

Sometimes, a game can go really smoothly. No one is talking in all chat... But then, the enemy team wins the 50 minutes game, and instead of writing things like: "GG! WP!" They wait until then post game chat and they do this:

1 joined the room. 2 joined the room. 3 joined the room. 4 joined the room. 5 joined the room. 1: Trash 1: noobs 2: you huys trash 3: YOU GUYS SUCK 3: NOOBS 1: learn how to play 4: ez money 3: * SOWNS 3: DOWNS 5: gold 1 blitzcrank who thinks hes good and insults others 3: RETARTS 6: gg 1: noob 3: LIKE POP TARTS] 3: BUT RETARTS 4: ITS IN EZ's NAME 4: E 4: Z 4: MONEY 3: EZ ASF 3: NOOBS 3 left the room. 3: KILL YOURSELF 3: PLEASE 3: DRINK BLEACH 3: YOU GIVE ME CANCER 3 left the room. 4 left the room. 6 left the room. 7 left the room. 5 left the room. 8 left the room.

Why? Because they know it isn't monitored and that they can say anything without consequences. if you want to report them, it won't leave a trace. This needs to be fixed, before someone gets hurt because they decided to "drink bleach and go kill themselves."
