Lemme explain. First off, don't flag things you disagree with. They break no rules.
Diancie, Volcanion and Hoopa weren't found because the event was in the coding; the Pokemon themselves were in the coding. The event is the data needed for the game to give you the Pokemon; the Pokemon's general information like its base stats and such are already in the coding which the hacker, Smealum, found. Same goes for the new Vivillon patters and AZ's Floette.
