Did Riot delete the warning System they had beforehand?

So i just remembered back in the days of season 4-6 sometimes I got warned that i got reported more than normaly in the frame of some games and that i should change my behaviour before it comes to punishments. I didn't receive any kind of warning like this anymore since season 7 and definitly not before my chat restrict i got this year and thats why im asking did Riot delete the warning system and if yes why would they do such a ..... move to remove the only System that can actually tell you that you weren't behaving so good the last days before something escalates. People allways say ''Accept the 10 day restrict as a warning'' Ye nice that the warning literally removes my rewards from the game and makes me play 8 Months to even unlock them.
