Baited into the permanent ban

So after fighting with depression and finding some sanity and hope thru League with hundreds of hours put into it.....all comes down to this. So meet this disgusting Nunu guy in my last game,and apparently hes ''soft trolling'' or whatever,so when he ruined the game and i call him out on that,he started being extremely toxic as far as saying ''hope your family dies... etc.'' and what not, now i was toxic in the past (and punished for slight bad words,basically quantity over quality) but never ever to that point of irl death wishes,ever (since i'm struggling with depression i can understand the real impact of those words). So i was a little bit on the edge this game, but only thing i wanted is for that guy to get reported. at the end of the game i get a pop-up that i'm Permanently Banned.....apparently he was duoing with one of the players in the team and they reported ME instead (i was passive aggressive a bit,saying ''dumb,good inting'' stuff like that,never a serious flame since i know the consequences) that triggered Riot's zero-tolerance filter which led to me being banned instead.......safe to say that i was very shocked and sad by that twisted outcome,so to all of you reading this....if you've been banned before do not get baited by others into perma,even a slight ''dumb troll'' word can get you harsh punishment. Worst of all that guy is still enjoying the game while wishing ''death and cancer to other's families'' and i'm out here unable to play.
