@Riot regarding my own behaviour

So, I've never been banned, not even chat restricted. However, I do tend to lose my cool at times. Especially during frustrating games (I tilt really easily when I play Kat because she's my favourite champion and I just want to do well with her).

Despite not having received anything indicating I was being toxic by Riot, I was wondering if there was a way to tell? Is there somewhere I can go to see how many strikes I have before getting a chat restriction? If not, why not? Wouldn't something like this be great for a preventative approach?

Would love your opinion on this.
