As long as the game itself actually creates the pokemon, then its not illegitamate. Its like lineage: two hacked pokemon's offspring will be legit, cause the game creates it; all it grabs from the hacks is 2 IVs off each. EDIT: I just saw, you wrote "unethical". Well, people differ in opinions (and are entitled to them) but speeding up a proccess to get things that are obtainable: theres nothing wrong with that. An athelete has to train, and then race: but the "training"/"breeding" proccess in pokemon has nothing to do with competitive battling (it does not improve your skills), so that analyogy is flawed (actually becoming a disanalogy).

Ontopic:
I would love to sign the petition, but according to the TOS you need to be of legal age in the U.S's laws. Im 17 from the UK, so I wanted to know what the U.S's laws are as to whether I am allowed to sign.
If not (and if as well), I will still be writing an e-mail in a very polite manner on teh subject of qualifications, regularity of tournaments and not even hearing about the London event (e.g. announce it earlier!).
