Riot's system is OP

So I was in a game the other day, I and wanted to try an experiment. The people on my team all agreed, so we tried it out. I started being excessively toxic to everyone on my team(part of the experiment don't worry) and I kept this up for a while. My team talked in all chat about how I keep being toxic to them, and to please report me. Then I used my charming abilities and started crying to the other team about how these people were all together and how they were being so toxic to me and they were lying about me being toxic. I eventually got the other team to believe me, and at the end of our game 3 of my 4 teammates got warnings for verbal abuse. This is just such a flawed system, that one person can be a dick all game and then be so convincing that he never gets reported and his whole team does and could possibly get banned. /sigh
