Could one poison the records by sending multiple samples of different blood sources attached to the same name? So the database query would'nt be conclusive, but you would know which test is legit. How would the ancestry testers react if I sent several samples in my name? Will there be a market for clean blood that you can use to confuse the records and get a sort of plausible deniability of identity?
