It wasn't generated legitimately, or legally. That's all I'm saying (because no one ever posted proof my Mew was hacked, either), and last I checked, that makes it hacked, like a Hall of Origin Arceus.
I did this here because I keep getting infractions posting on the blacklist. Apparently, you're an idiot to get a "respected" member in the blacklist even if he did trade you a hacked Pokemon.
