Constant follow-ups of small chat restrictions

A few weaks ago, I received a chat restriction of around 50 games as I recall due to strong toxicity which I agree was about right.

However since I have gotten over it, I have been working very hard to try improving my behavior in-game and I believe I was able to get rid of my toxicity.

Somehow lately, I have been getting a lot of successive small chat restrictions and I have no idea why since I have shown about no toxicity in my last 50 games. It makes me feel kind of very sad since I am actually trying to improve and Im being rewarded for my new behavior with other slaps in the face. it feels like the current no tribunal system seemingly based on the amount of reports you get has a lot of loopholes and it is very discouraging that I cant seem to get out of the loop.
