The pokemon was not as described, not having it's memories. You can see at the top of this very page how that is mentioned as a potential sign of it being a 5th generation pokemon hacked to receive a pentagon. I tried to trade your hacked finneon back, telling you why it was an issue, for the plusle (which I assume at this point is probably also hacked). I then gave you the opportunity to just cancel the trade and keep your cloned versions of my pokemon, returning the chimecho/clone of chimecho since you didn't seem to want to cooperate. You refused to do even this, so saying that you will "give him back his pokemon, tmrw" is too little too late. The fact that you lied about the memory of the pokemon, knowing what the right answer is means that you more likely than not, are knowingly traded your hacked pokemon as legitimate. That alone is a major offense.
