it doesnt matter who traded them to you, whoever received the Jeremy pokes in the first place will have had the haunter and machoke evolve during trade as you couldnt stop their evolution when traded from the nintendo rep since during the event no everstones were used. therefore as DarkMSS said above, they are hacked
if people offer them in their wi-fi trade lists then just reinforces how annoyingly dumb people are when it comes to event pokemon, enuf said
but great that you took the time to put your event pokemon (even if they are hacked) up here, coodoss to u
