Lmao ranked que bans

So just playing ranked with my friend as always winning some and losing some. One magical game I died before minions spawned because some reason their whole team was sitting at top bush. Then my team flamed me and started saying things like "he said he was going to intentionally feed" (I actually never said anything yet that game besides just regular chat in matchmaking, they were just being toxic trolls). They intentionally fed bot lane 20 kills. I got 8 kills and only died 5 times. They spammed chat all game asking to report me when I wasnt doing anything and were demanding getting me banned from ranked que. Well logged back in a day later and I am banned from rank que. This new system is crap and I really feel like going and being toxic in the normal games its forcing me to play before I can play with my friend again because I do not want to solo que and win draft normals to play this game. GG riot encouraging bad behavior because they dont check anything themselves and rely on tribunal trolls.
