Any way to personal players rating ?

Some ppls toxic, some play under "things", some just... strange.

I know only one way to remember players for future.
I add to foe "bad" players, to friends - good.

But its only one level system.
I looking to more precise way to store my previous expirience.
Ideally - give any player my personal (invisible to other) numerical rating from -10 to 10.
May be any mod available for it ?
