What makes this game Toxic, isn't the people being toxic.

It's the people who condone the actions of toxic people.

People who applaud people who feed/flame etc. In my current game I have an intentionally feeding Viktor and an enemy teammate, Zyra who is applauding him for his actions, saying she will honor him for having toxic teammates. While this could be a joke and Zyra has no intention of doing this, this may be a tactic to make us rage, but this tactic is stupid and only promotes toxicity.

You don't give candy to a child when it is misbehaving just to spite the child's mother.
