And they are still not releasing Pokebank. Harsh.
One thing I can see is this: I think the people managing Pokebank can at least monitor and or collect data about Pokemon Being uploaded into it. As you already know, hacks are able to pass through it. It CAN block Pokemon, if it does not match certain requirements. Unusual-Impossible Movesets, Impossible Abilities, Hacked shinies, Illegitimate fateful counters that are false, Impossible Pokeballs where a Pokemon is contained it(Imagine a Tornadus in a Love ball) and other stuff. Though Pokebank is at Version 1.0, so my guess is that after the Pokebank's free trial(me) is over, maybe they'll release it. Or if they can move to another server. Remember the time we crashed Global Link the first time during Black and White? Yeah that.
As to release an event Pokemon, You're getting a free Celebi anyway, who cares about that, demand extra months for Using Pokebank! That's much better in the LONG run. Or Demand that the first year of usage is free of charge.(OK that's a little too much, maybe a month or days of downtime where everyone was cut off from Pokebank)
I've always wanted to do this, so forgive me:
I FEEL LIKE A PREMIUM BOZZ. MWHAHAHAHAHA
Note: I got the shiny charm as soon as Pokebank released. I captured and sent every Pokemon I could from all past games and stored them in my bank. Now I see SHinys......on rare occassions. Which is the same as usual.
Note 2: Apparently I have way too many shinies from past experimentations and I look back now, I feel so happy. Even though the shiny Pokemon I breeded-caught had less than average stats and beneficial natures, they're still my PRECIOUS
