I visited this site, and uploaded my DNA data. After having felt misled by the sign-up process, I then deleted it.
I was surprised therefore to receive an email with the subject "You have a new DNA match". After spending a chunk of my time logging into the site and looking for further information on this match, I was reminded that I had deleted my DNA. When I enquired my I had been sent this email, I didn't get a straight answer, just confirmation that my DNA isn't there, so there couldn't be a match.
The email I was sent appears to have been misleadingly titled just to attract my attention. What a waste of my time!
These people might know about DNA but they are either desperate for business or unscrupulous in their marketing, and best avoided.
