Chat restricted because toxic player reported me?

I know for sure I wasn't chat restricted because of my negative chat. There was a Tahm who was TOP in a recent game that kept mocking my every move and insulting me, and rallying the team to report me just because we ALL were doing bad and some of my ganks didn't result in kills. He and probably one other reported me because they didn't like me.. Now i'm chat restricted? Why?!
