That depends. If you have somehow bypassed the anti-piracy measures on a porygon to download one illegally, you could face hefty fines or jail time (depending on your country and its interpretation of pokémon theft), never mind a lawsuit from Silph Co. itself if you attempted to distribute an illegally downloaded porygon. In short, with the government and Silph Co. itself, I would say a lot of trouble.
However, should it be of any comfort to you, when it comes to the storage system and its involvement with all of this, you would likely receive a high five and a job offer, given my partner’s recruitment history. —LH
