14 day ban, without previous warnigs. Fair?

I received a 14 day ban for being toxic, which means I won't get end of season rewards. My only question for you guys are: Is my ban really justified, seeing as I got no previous warnings or chat restrictions? I really didn't think I was being that toxic, however I would've definitely changed my behavior if I got a warning. Here are the chat logs on my reform card: [img]https://i.imgur.com/9F2Kex9.png[/img] (note: The first "%%%" was to a friend I qued with. Everything else was targeted to a toxic darius I responded to. And no, I didn't actually report him)
