If it's a Wondercard Vivillion, at least it's in a Cherishball and fateful encounter so it won't be an obvious fake...
Plus, you won't be able to deposit in the GTS if it was a fateful encounter.
True. This still wouldn't prevent people from trading Shiny Pokeball Vivillons to each other though. And as Kaphotics said above, it's possible for them to turn off the "make shiny" code for this particular Vivillon so it's weird that they didn't. Maybe they didn't care enough? They might turn it off for the next Vivillon pattern so at least we won't get more people claiming Pokemon is ruined Forever.
