Sounds like Versilify is just full of his usual shit. Pokemon data structure only contains info about that one pokemon and don't carry marks of it's parents. If the mon is bred ingame and hasn't been altered since, there's no way their systems will know it has unlegit ancestry.
These bans just seem to be about GTS being fucked up. Get any interruption, from your end or GTS, and you get banned. Nice work GF!
