Why do i get reported so much? ;(

Dear riot This is insane I get reported in a lot of games for doing absolutly nothing i think it is really dumb just because other people arnt having a good day dosn't mean they need to make mine worse. Literally in a ranked game i was being supper positive because i was going 3 kills 5 deaths so i was trying to like act like it wasn't a big deal and forget about it and play the game so i decided to say good stuff to my team when they did something good like when we win a team fight i would say GREAT JOB TEAM and stuff like KEEP IT UP. And at the end of the game we won and my team said to report me because i am a baby! like wuttttt. I got reported so many times for reason like this and people lie and say i have a negative attitude. I also got reported in 3 custome games for negative attitude because i was winning the game in a 1v1 and my opponent got so mad they reported me! so riot please i dont want to be banned for stupid reasons that arn't real. :^(
