You have the ability to block specific members from contacting you via message or invitation.
To enable the block, select Block from the message menu that appears in the compare view of DNA Relatives or Your Connections:
Blocking does not automatically remove a sharing connection; to unshare, visit Your Connections and click the "Remove connection" link after selecting the profile with whom you would like to unshare.
To continue communicating or to view previous messages, you can unblock the profile from the message menu.
If you received a message that is inappropriate or that violates the Terms of Service, please let us know by providing the content of the message and the name of the sender to Customer Care.
