I did 23 and Me but under a fake name. It correctly identified me as a 1st cousin with my cousin, whom I had no idea had already taken the test as well. It was very very spooky, and I can see how useful this would be for law enforcement. At some point in the future, you can drastically limit the number of people to search for based on DNA to a single family tree, if enough people submit their own DNA. It's scary. It's exactly like your contact list. Facebook doesn't need you to give them your phone number. They just need 1 out of your 500 contacts to upload their entire contacts list so that they get your phone number. The law of numbers is completely against you and your privacy is already violated completely because one of your friends did it to you.
