Int feeding ban

I got banned due to intentional feeding - can someone please explain how - my game was 4/18 - jungler was afk and top was getting nailed and camped by mid/jungler and their top - i farmed and did my best. I end up getting banned for dying too much in a game? i got reported cos my team was trolling - it was a premade and their jungler was their friend - and they kept spamming in all caht to report. I'm so disspointed in you riot - your system failed hard and this is a perfect example as to why. You'rre banning people left and right for no reason - look at my history in this account - it will show otherwuise that i dont feed or troll - yet all this good behaviour (had access to rewards) - no flamming - no cursirng - always help and providing thoughts to others - i end up getting banned over one bad game - and yes i did play poorly and a bit too aggressive . look atm team's score- it isn't that better - i atleast secured 4 kills - other trolls on the team were at 0/9 and didnt get anything? and why? cos they are a premade,

So much for improving the community where you are keeping trolls in the game and banning decent players - now i really know wat lol stands for "lol''
