In light of all the GDPR and serial killer DNA angst I thought it time to re-check what was shown to others.
I admit I was surprised to see that for living people who had DNA tested that even if the viewer was not logged in, the fact that the living person being looked at had tested AND their potential cousins who also had, are all shown.
Presumably only for those with privacy options set to show family tree??
Although the DNA features are very high up in my list of things why I love WikiTree AND I am a fully supportive member for DNA testing, open family trees and sharing with DNA matches, I would suggest that the DNA tested section be treated like comments, edits etc under the Collaborate section and be marked as needing to be logged in to view.
