Should I have been banned??

So I was playing league with a group of my friends and we played a game. I picked zyra mid, didn't really do good. But the problem started when about 5 or so minutes before the game ended, I went to go take our red buff because it was up and no one was around to get it. I get red Isn't useful on zyra, but our yasuo got very triggered by me taking red for some reason, and we argued for a hot second about it, and I'm pretty sure that's why he reported me and i got banned. https://imgur.com/a/bgAaj https://imgur.com/a/wadpL

Now I did say %%% at the beginning a few times, (and that's probably what triggered the automatic banning system) But The first time I was calling MYSELF a %%%, and the second time i was calling our thresh and kindred, who are two of my friends in my premade group a %%%??? I understand that the use of that word Is frowned upon, but i used it on myself, and my premade friends? Yasuo didn't even report me for the usage of that word, he reported me for "trolling/griefing" because he told me i was griefing when i took red.

Should i have been banned?
