How tolerant is Rito to offensive names?

Since im playing (S1) I've noticed an extreme change duo to summoner names. They become more offensive from month to moth, some examples containing words like N*gger, B*tch, Wh*re and way more. Also the Clan Tags become offensive, I've seen several tags like "Anal", "Slut", "Wh*re" and way more. Now if those people would act pretty friendly i wouldnt feel really offended by it but those people with even those names seem not to be punished by Riot, I'm reporting them after every game i see them and since im playing (S1) I've had 1 confirmation, that somebody got banned. 1 Confirmation within 6 years. They don't even force them to change the names... What's your opinion about that?
