Can Toxic Games NOT stack?

Hey so, i recently got banned for 14 days, now im not saying innocent, looking back on it, i really was toxic. But when you have a team of nothing but chode chokers, you kind of want to whack their heads in with a baseball bat but thats not the point. For 14 day ban, it cited my one game on my chat restriction, and then two others that were from almost a week ago, games that were cited in my PREVIOUS chat restriction, one I had already burnt up and moved past. I'm not asking to be unbanned, i frankly dont care, ill just play on my smurf, it needs runes anyways. But I do want riot to fix their god damn system because im not sure if the bots wouldve flagged my account in first place, which i find to be an obvious misstep for people unlike me who get drunk sometimes, and can have a collection of games riot can use against them at any point, chat restriction over or not.

tl;dr you can get flagged for games like weeks old and it can fuck with the """"reform"""" system
