How it worked is that two prefabs were distributed:
One was distributed to the thread, every thread for like 2-3 weeks. Another was posted to some associated discords the day before. 

The one that was posted in the thread for weeks let you through, and the other summoned a giant jannie that yeeted you into a discord tranny cage. 

The actual event was then held somewhere else and everyone turned up. At least until some discord tranny crashed the instance over and over because they were mad about being called out.
