Well, technically the person is a real living person who have uploaded his DNA to Ysearch or Mitosearch, and these was transferred to Geni as part of the Geni/FTDNA deal, but because of privacy rules etc there is no name on that profile. Internally the system only knows the email-address.
Since Shaun Rainey have a 90% match on this (67 markers matched out of 67 markers) it is probably himself. Since he also have a blue profile match to this HIDDEN person it is probably caused by an email-match, so he should just approve the merge suggestion.
Shaun: Have you used Ysearch or Mitosearch?
