PSA and publicly available information?

[tschock]

When someone submits cards to PSA for grading, is any of that information public? Possibly through the the registry website (or elsewhere)? Asking because of a strange situation.

About 2 years ago the owner of a local auction house I know had a consignment for a large collection of tobacco cards along with other 'newer' stuff (including a '52 Mantle). So he had his nephew who knew a little about cards send the cards off to PSA for grading. After about 18 months the cards came back graded. A short time after that, maybe a few days to a week, the nephew gets a call from "a major auction house" asking the nephew if he would be interested in consigning the cards to this major auction house for sale. The question that was asked to me was how did the auction house get the contact information?

I don't believe the nephew created a registry profile, or even if he did, his name/location wouldn't be publically available unless he used his name or some other 'searchable' information, such as his real name or the local auction house name.

Am I missing something that is not shady in nature?
