Did you even bother watching the video or reading anything associated with it because if you had you'd not have typed that wall of text you wrote that's disproven by everything there. You keep stating about biases but use your own without hesitation.
The presentation was hosted by MIT and the Berkman Center for Internet & Society

Featuring:
Jeffrey "Lyte" Lin, Lead Social Systems Designer, Riot Games
Carl "StatusKwoh" Kwoh, Producer, Riot Games
Moderated by Justin Reich, Visiting Lecturer, MIT Scheller Teacher Education Program and Fellow at the Berkman Center for Internet and Society
As part of a team at Riot Games that includes statisticians, scientists, psychologists and developers, Jeffrey "Lyte" Lin and Carl "Status Kwoh" Kwoh are responsible for understanding and solving toxic player behavior. The Player Behavior & Justice team at Riot use the latest research in behavioral, social and cognitive psychology to make major changes and minor tweaks to the League of Legends environment. From the player-driven Tribunal to the Honor Initiative, League of Legends' behavior-focused features reduce harassment and reinforce positive actions. Toxic player behavior is one of the biggest problems in online gaming today. In this interactive discussion, Lin and Kwoh, along with Justin Reich of the Berkman Center for Internet & Society, discuss how psychological insights can create greater civility in a networked world.
There's also the GDC presentations where they talk about it but less in depth.

So if you want to claim bias and misinformation then I'm sure the people at MIT would like to have a word with you since I'll believe their opinions and credentials over your highly biased opinions. So if you want to try and use science and facts you better be able to back them up. Trying to use made up facts and examples won't fly here since it's been tried before so post data and actual facts for your claims.
Oh and here's the link to the Berkman Center for Internet & Society (http://cyber.law.harvard.edu). and the
MIT Game Lab (http://gamelab.mit.edu) so you can contact both of them and tell them they're full of it based upon your scientific knowledge and observations.
