So is this (or should I say 'Rong')-
To help with such an immense and murky history of comic books, CGC has teamed with Rob Rong (@ForeignComicKeys on Instagram), a leading international comic book collector who provided his expertise and extensive database to accurately identify and categorize the country of origin and publisher for each comic, two critical factors in certification. Additionally, CGC researches the contents of each international comic book it grades, which may vary widely for a particular issue printed in multiple countries.
I don't want to denigrate a guy with an Instagram page just because I've never heard of him, but is he the only one they consulted with? What about the GCD? I know it ain't perfect, but at least they're trying to maintain an accurate record.
