was told players cannot be banned under certain conditions

so i just got through a game of league(trying to bring back jungle) and had a very rude yasuo on the other team. they won but he felt the need to end the match with gg losers. when he was informed of his report he responded with,(i cant be banned i have over 300 honar, honared players cant be banned) well i assume this to be nonsence, i must ask if it is true as ive reported players that were incredably toxic to the point of being reacist and seen them in matches again in the same week.
