Chat restriction system promotes abusive behavior

2 games ago i was playing anivia mid and was dominating a veigar. He was talking all kinds of crap about how terrible i am and then i got camped. I tried to tell my jungler that i was having a problem staying in lane but he just refused which ticked me off. So i looked to bot lane and ganked them multiple times. Once i helped them i got raged at hard by legitimately everyone int he game besides the person i was in skype with. Every single time any of the enemy players got a kill or took an objective or did legit anything then they would brag and spew bullshit constantly in all chat. The fact that i am to be chat banned for telling them to shut up and stop harrasing me and my team is pure and utter insanity. Where is the balance in a system that punishes one for sticking up for themselves. Its like riot games is a principal and you keep going to them for help becuase your getting bullied but all they do is tell you to avoid them. But when it gets to the point where you cant take the abuse anymore you fight back and instead of the bully getting busted you do instead becuase the bully has more friends. So thank you league of legends your the real hero, you pick on those that are sick of getting fucked with and that finally push back. Way to really solve the abuse.
