The Blue Strip with the words "Confirm this relationship with DNA" seems to be in a sense intimidating some folks, who are taking it as a commandment.
I am quite sure that was not what was meant.
I do not at present have a great alternative phrasing to offer.
But would like to suggest folks think about it -- we do not want to have folks avoid working on Geni because they cannot obey that "commandment" (or do not wish to, due to privacy concerns or whatever).
See, for example, https://www.geni.com/discussions/176473?msg=1192387 where the poster worries about being able to find appropriate DNA connections, and so concludes "I'm willing to help, I just am uncertain how much help I can be." -- and when asked, explained she meant help with this World Tree Project here on Geni.
