Do I take it you go around wearing gloves or perhaps a bunny suit to avoid leaving DNA to avoid leaving exceedingly personal idents everywhere you go?
I do give you credit however for signing as Jay along with "frutioftheloon" to avoid the comment that it is no more identifying that "Anonymous Coward". I posted as AC more out of random chance than any desire to hide a virtual identity.
