Group of Hackers?

So, I was recently permabanned, and when I looked at my match history I found 2 games that I didn't play. I main adc, and jg, they played zilean and xerath u can check my match history, and see those 2 games. I notice that both games were with the same group of people, and I was about to report them all. Then when I checked their math history, I realized they also didn't play their mains, so now I believe they also got hacked. I'm not sure if rito can do anything about this, but I wanted to spread some awareness.
