Permanent ban

I feel like I need to say this, I was playing a game today and yes I fed that game and it wasn't intentionally my team was telling me some real toxic stuff like "kys" and/or "uninstall" just cause I was bad with singed and so I got mad and started feeding intentionally, they wanted me to fight a teemo as singed when I don't even know his mechanics but that's not the point. This is my 2nd time getting banned and I got perms banned and idk why, those people were being even more toxic than I was. The game wasn't even in ranked so I thought that losing a match in Normal wasn't even that big of a deal. Why is this system like this. I've only feed intentionally like 3 or 4 games in my whole league years and I wanna know why riot takes numbers over opinions. If your team wants you to go afk so they can report you for afk or tell you to go back to the lane your were feeding in so that they could report you for feeding would you do it? Well that's what my life is in 60% of games. I was practicing to get out of bronze but I gues Ill never. Get to get out and I'll just stay like that cause I was too toxic according to league....just cause 3 people reported me from my team they are gonna ban me for life. I spent hours on that account and played this game to cheer me up but only thing it ended up doing in the end is breaking my hart cause they barely look at what people's opinions are and yet they are so quick to judge the numbers. I gues no one would know what it's like to play with bronze players cause they are in silver or above.well I'm pretty sure this won't even change the fact that I'm perma banned but I just wanted to put this out there.thx for fixing most of my bad day league. The money I wasted made my day bright every time I saw myself with that skin I bought but now I gues I'll just have to find another game.
