Riot i swore in game? No ban?

Yeah i was playing last night and i told some kid to "stfu" where is my ban? Im a huge activist in trying to clean up league and remove toxic players, i'll serve my punishment im just asking if it can be a 14 day ban instead of perm ban. Ive put some money into this account so i dont want to loose it, my bad guys it won't happen again. Keep up the great content :).
