Chat exploit

Chat exploit (spamming random characters) – results in client crashing!
I want to warn everybody with an exploit I just experienced in a normal game. It started with random characters spamming in the all chat and everybody was confused. Then randomly clients started crashing (was on skype with teammates) and after a while it happend to myself. note: Nasus never typed anything in all chat.

TL;DR If you see random characters being spammed in chat, DISABLE ALL CHAT!
