I'm sure that observation doesnt apply to just KO's mate.
but yeah, it is a shame when people unsuspectingly get ripped off from buying KO's (especially expensive KO's) thinking they are legit, but life is a learning process. We have all been ripped of at some stage or another and we need to learn from it.
But on the opposite spectrum, there are some that knowingly buy KO's, thinking desperately that they can never own a legit MISB G1 Swoop (for e.g.), so they opt to pay the higher (but still cheaper) price and get MISB KO Swoop right then and there.
