Help Me Understand To Why I Was Chat Restricted

I recently got chat restricted for 10 games and I know it's not as big of a deal as a suspension or a ban but I'm scared that I will lose my account considering how much I've spent on the game and how much I've advanced the account (level wise + masteries and honours).

I got my chat log from the match I was punished from and reading them doesn't really show anything that violates the rules which is why I'm confused about why I was punished. The chat log simply shows me attempting to stop the argument/issue because the opposing party wouldn't stop typing in chat and it was during a ranked match (in my promos as well) and I was trying to win. Not only that but before everything went downhill, my chat logs clearly show comedic purposes and I don't know if that contributed to my punishment. Anyways, if anyone could help me understand as to why I was punished so it'll be avoided next time. Thank you <3
