I did the HP Grass Zapdos for a friend on GameFAQs before having it redistributed on a GTS. All of my Pokemon are freely redis, so they are bound to make their way into many a trader's hands.
I've made a few enemies that might hack it to tarnish my name / IDs, namely a few from the PokemonSecure.com event community. This met location was obviously tampered with, as my file copy before redistribution is fine.
