For as far as I know, these people only have legit Pokémon:
Flora, -Red-, stonehenge22, UUWarrior, sophies, DarthChocoboz, Eminem, The Agonist, dela_Cruz, Syberia. Not sure about those others since I never traded with them. Bond's stuff looks legit to me, only he's acting like a bitch xD
And that Slowpoke was just for fun, wanted to replace my older Slowking, that was waaaaay before I knew about IV's and stuff :p So now I've got a better one. :)
