Why did the Bumych delete all of his friends?

According to Overdrive, Bumych blocked Aunker, Fander and other friends because they didn’t listen to his requests to play full fox. It was important, because this game depended on whether they would make the playoffs. Unfortunately, Aunker and the others were running around during the game and having fun, causing Bumych to decide to block them. It was not a very good move from Aunker.
