Bad games in silver

So I just had a game where I experienced acc intentional feeding from this leona. I want to know if I can get banned for some of things I said. I muted her from the beginning after she called me a dumbass and later I told my team to mute her. I then told my team to ignore the leo when people were getting angry at her. Then finally when I cracked I said.

"Leo do you feel good about feeding?"

"Does this make you feel good about yourself."

Is this bannable?

Also the leo might not look like she inted but what she was doing was splitting and basically just dying every time because she would overextend. She would never group and harassed team "apparently because the team said she was".

I understand that this was toxic and I did kind of over react (btw I havent got banned I just want to stop myself from getting any more toxic)
