Are you talking about this profile: Private ??
That is now a claimed profile - geni no longer shows the actual e-mail addresses - which is very annoying, since it means I cannot let my relatives know which e-mail they used - but before the "@" it starts with "l" and ends with"e" and after the "@" it starts with "r" and ends with "m".
No idea if someone accidentally put the e-mail invite in the wrong profile and the person would like help moving to the correct profile or if it was done on purpose.
You might try using "Send Message" on the profile to ask him who he is, etc.
If you get a response, and he is looking for help to move to the correct profile - then you can try posting in https://www.geni.com/discussions/178003 and a Curator can perhaps help, or offer advice.
If you get no response - or are sure it was done intentionally - then
- go to the profile - click "Actions"(upper right) - then choose "Report" - but I have no idea if better to choose "Claimed Historical Profile" or "Deceased" - again, suggest post that question in the Discussion I provided link to. [think "Claimed Historical" is for famous folk - "Deceased" usually gets quick action - so possibly that is better, but not sure - if you do go this route - put some info in the box explaining how you know the person is not still alive]
