I brought some hacked Pokemon into the Battle Spot and it worked?

I brought a hacked Shiny Mewtwo, Rayquaza, and Groudon into the Battle Spot (Aware that they are hacked) and it actually went through! How? Why?

I’ve been researching this using my AR and Gen V games: the checks can be a little vague. I used my AR to catch a level 1 female Bulbasaur in Nuvema Town with it’s Hidden Ability, and PokeBank didn’t bat an eye lid, but my Chikorita with it’s Hidden Ability was blocked. Battle spot wouldn’t check any more than Bank, maybe less. Basically what I’m trying to say is, you’ve just experienced first hand how underwhelming the checking system is (which makes me wonder how all those people got banned in the first place).

I’m sorry but I have to disagree with the other guy that answered, yes GF has no solid methods to check if a Pokemon is legal but you are definitely playing in open battle, there the game doesn’t check if a Pokemon is legal or not (unless is impossible to obtain like hydro cannon charizard) because it doesn’t matter, there’s no ladder to climb and people don’t practice there. on the other hand to answer the question below: most people got banned using hackmons on ladder or using Pokemon impossible to obtain.
