Account suspended even with chat disabled

I got my account suspended for 1 week , one month ago . After that i played with the in-game chat muted . Yet, i still got another suspension LOL. How is that possible?? only cause i did lot of games so i took lot of free reports? ( u know ppl get mad when they lose so report everybody) . I openeded another ticked but i know i will have an auotmatic response from an AI. Im so frustrated from the the situation. I was afraid to use the team-chat in game now im afraid to play too much! more games = more reports. that’s it. Just cause i will lose also this account … again! how is that possible ? what is happening??
