Whats going on in Riots head,can someone explain this to me,what was so incredibly offensive here that it deserves a chat ban,please,i want to know,and i want to know why Xerath,the enemy who STARTED flaming after he began to lose his lane didn't get a chat ban? The worst thing i've said is "Loser" and thats exactly what he told me,after he managed to kill me by having bot and jg come and help. I've said nothing that he say to me,he started flaming first,started rank shaming,started calling me a dog,a loser,etc. but i get a chat ban,why can't we see his messages,i really don't think its a fair system where even having a little banter,not outright nasty flaming is now a punishable offense,can someone tell me how to write a ticket,this ban is bullshit,i want the guy who issued it to me explain it.
