3 years until a chat restriction... now what?

I’ve been playing for 3 years and I’ve been pretty toxic throughout... Now, I’ve significantly reformed since 2 years ago where I would be cursing out every single game, but a couple games a few weeks ago caused me a 10 game chat restriction.

I’m sure I’ve amassed over 10 reports before this restriction came into place. Now I know my account is on thin ice, but how strict is it? If I get one singular report am I going to get a 25-game restriction? I know that after a 14-day ban, ANYTHING will get you permabanned, but is it the same in this case? I’m all for ignoring all at the beginning of the game and not talking; I’ve won considerably more games and generally have felt better and less tilted about losses when I do this; but that makes me VERY worried because people in my very low ELO will report for literally no reason; once my support reported me for playing too safe in lane without me saying anything offesnif my account is in bad standing will that one report be considered restriction-worthy?

It really doesn’t seem right that I can get over 10 reports before one restriction, then have only ONE report cause the next punishment. If anyone could give clarification on this I would appreciate it, thank you!
