Finding it taxing not to get perma'd

Just got done with 14 day suspension after getting irritated by a dude who trolled me as ADC because he got autofilled support. He went sona with TP, gave a couple kills to bot lane, then left me to get steamrolled. Then I come back from my 14 day suspension, and play a normal, and get to listen to my top and adc flame me and talk about what an "idiot" I am for half game. I have literally said nothing to them, not joking, did not want to get account banned and I know how easy it is, so I say absolutely nothing. They're still trash talking me, while I am 18/5/16 as warwick. Now I understand, it is wrong to just bash into someone for being bad when they mess up... but I've never been one to turn the other cheek when someone picks a fight with me, and I would totally be down to take the lose if it came down to it, to argue back, ranks not that important to me. But why does MY account have to be on the line, because I cant say anything back to someone blatantly trash talking me, or trolling me. I've actually had an account be perma'd, because I was playing with a IRL friend who doesnt really play, and I had a jungle 1/4 lee sin trying to flame him because he was "bad" when the lee sin was playing terrible. This games asking you to alter your personality to avoid banning, is far more stressful than if I lost the occasional game because someone chose to flame instead of play.
