I first though pokemonmaniac was nintendo1252's alt but it seems it isn't except if he figured out alone why I knew his contribution was hacked.
So...
Korean Meloetta from Pokemonmaniac: Legal
Korean Meloetta from Nintendo1252 (now removed but downloaded by many): hacked
Korean Keldeo from Nintendo1252: hacked
By the way...
Korean Victini from Nintendo1252: Hacked
Legal contribution most likely hacked (no proof except that it's very logical):
Korean Darkrai
Italian Darkrai
Korean Reshiram
Korean Zekrom
Korean Kanto starter eggs.
Why it is so logical that those legal Events are hacked:
The only difference with Japanese contribution and those Events are: PGF title, OT, ID and date.
He never messed up that part except once with Spanish VGC12 Larvitar, wrong title proved by another contribution a few days later.
If Meloetta, Keldeo and Victini have been proved hacked, it's only because there is a weird difference btw Japanese and Korean legitimate PGF.
Now, you know.
Thanks for reading
