Banned because, one day, you shoved a Psyduck put of the way while running to a restaurant. That Psyduck was on it's way to meet it's lover to propose, but fell on it's head to hard that it had to go to hospital. Consequently it's lover assumed that Psyduck didn't love her anymore and committed suicide by jumping off the top floor of the Silph Co. office building. Psyduck became so depressed that it ended up homeless and living on the streets, begging for change from passers by and eventually died from massive heart faliure.
Just remember: you did this.
