"From the quarterfinal round forward results must be verifiable therefore films must be posted by the winning player for all duels from that round forward. This also allows for film study by those hoping to improve their skills. Failure of the winning player to post films in these rounds will result in the win being awarded to that player’s opponent who must then post their films"
Krup would not be expelled from the tournament. Rather, as per the rules, he would forfeit.
In general, I would say Spek should have won last tournament, and Krup should win this round. However, when a rule is enforced, regardless of the degree, it should be enforced to all.
