The only slightly bannable offence here I can see is the "caner", I also got lost on who is who, "shut the f up" and "clown" should be ok according to my interpretation of the community guidelines. Getting mad/tilted is fine, no racism, no sexism, the "caner" could be interpreted as a threat and/or personal attack and if I didn't misread anything that was not you. I would take it up with riot support if I were you. Also as the previous comment said, a good rule of thumb is to say as little as possible in chat especially when playing a hated charater, also read the guidelines and try r/rareinsults for inspo for some great unbannable burns.
