Though if neither a father nor his sons have submitted their DNA, the service will lack all that Y-DNA though, right? I’m glad I made the right decision to not send in my DNA to those sites, despite my sisters hounding me to do it after our dad refused, lol.
It’s a shame though, because family genetic networking is interesting, but it just goes to show you can’t trust these companies. (Even though the company didn’t really do anything truly wrong in this case, as it’s simply users reusing passwords, they still should have been better/more proactive especially with such sensitive information)
