I mean you could try to find the large known leaks and go through them yourself
People just cross reference them and sell individual ID packs one by one
There were 15,000,000 people in the Experian leak alone. Most of that information is still valid, we've just gotten numb to it.
Merchants that care about customer support and reviews will just replace an ID for the consumer if its been used before
There isn't a way to try to find who is in a database without the source databases yourself. Merchants don't tell you how they found the aggregate data, they just have reviews from people that say if it was accurate data or not. You could try and ask a merchant if they have a particular person, but I doubt many merchants have a way to sort that themselves, as the files are no longer in a parseable database by the time it reaches them. The organized networks are corporations and conglomerates with separations of knowledge and duties.
All you would be able to do is purchase a FULLZ and get what you get.
