Yeah. The thing is he lied about the whole story. Said he "found" it recently in his Fire red ROM and that he obtained it 6 years ago at the event. Well Matteo has had it in his thread for quite some time now, same IVs, nature, etc.
He then continues to suggest it is legitimate because it passed a few hack checks. I think he posted the same thing like twice in his thread, PM'ed me once, and VM'ed me once just saying they passed a hack check.
