I mean, what is your threat model, and what are you trying to get out of DNA/ancestry services?

If you're worried about getting arrested for one of the many crimes you've committed, and you want to meet far-flung relatives, you're kind of in a bind here. Assuming unlimited cooperation between the police and the DNA/ancestry services -- which your threat model in this case would require -- even if they don't have your name or address, they could fabricate a half-sibling/double-cousin in the system and have them reach out to you. What, are you not going to talk to and eventually meet the cop pretending to be your previously unknown half-sibling/double-cousin?

My threat model is about the changing world, essentially activist who feel like having right to tell who lives where. I usually pass by the look, fail by the accent and I intend not to have another data point they can use.
