ESL put on two DOA events this week, one in Japan and one in Europe. The Japanese event went fine and there was no controversy there; but the European event went down a different path that involved one of the most popular competitive players getting screwed by a random.
There was little to no moderation in this event so the player was quite the crafty exploit. @Gehaktbal also provides proof of his lagless victory in another video. This is something all players should be prepared to do if they plan on participating in any online event as they become a more popular option for those that can not travel.
UPDATE: After displaying the proper evidence, ESL has overturned the ruling in Jim's favor! Congrats, Gehaktbal.
