VK are not obligued to keep up with everything going on in the esports scene of other regions, it's very much possible they didn't know about those rulings.. If something like that happened in a major event like Masters and they still did it then I would have blamed VK. And since according to reports stating that the exploit isn't even listed in the rule book, I think it was an unfair ruling from Riot.. If they can stop a game for 20 minutes for a skill jump then they could have done that yesterday too. Atleast be consistent with how you handle stuff.
