Is there anyway to get unbanned early for being toxic?

I made a stupid joke in game but wrote %%% after it, and my adc was super toxic so they just reported me and him bot lane. He didn't receive a ban but I did. I honestly wasn't being toxic I just made a stupid joke. I did tell the guy on the other team to cry me a river but yeah he was spamming all chat. Ok to be clear on what I wrote it was the abbreviation of the F word for homosexual's.
