Can I speak to a Riot emolyee in live chat i dont want to be banned

I just finished a rank game . I had a mf on our team who told a player to “kill yourself.” I told the enemy to report Miss Fortune. Enemy Brand asked what she said , and I told him. Enemy Brand wanted to report me and tells me to enjoy my ban since I said it. I told him false report can get you banned and I was repeating what MF said. He tells me he been banned twice.I’m not sure how banning works. If a system automatically picks up words . I just don’t want to be banned. I already used the in game report. I also screenshot by taking the picture on my phone of the chats.
