Got chat restriction aswell as ranked restriction

Okay, I've been playing ranked quite a lot lately and I've basically been wrecking every single enemy on toplane, for some reason I received chat restriction for 75 games and ranked restriction for 35 games. I have got no idea why I received this punishment, I haven't even been flaming, I've only replied to people according to the situation. Is there any concrete evidence that shows my toxic behavior or did I just get reported for wrecking the opponents?
