shouldn't you know your punishment history??? (unless you buy the account)
If I get even chat restricted 5 years ago (or some random years), I'd still remember I received it even if I cant recall exactly when.
It's an upsetting event most people tend not to forget. If you make a habit of continuously getting punished over multiple accounts, then I can see forgetting your punishment history is a thing.
As for where your "reformed" toxic meter go, I can see the reason Rito will not give it to you so people won't try to play with the meter and be as toxic as they want until they are near that punishment line.
