The pitch by various ancestry operations is to send in your DNA by spitting into a vile and they will tell you your ethnic background. Sounds nice, but they then keep it. Why? The greatest danger is that such info can be turned over to the government at any moment. Giving up your DNA is actually giving up your entire family. People have been arrested because their DNA has been traced thanks to some family member who the government has in their database.
