According to his profile page, he was last seen at 11:43 on the day he made the post.
If he returns - fine we can try to help him.
If not - I don't think we will worry.
I wondered whether it was just a phising expedition and interpreted the posting of a gmail account as a flag. His request for direct contact, rather than through the site, is consistent with phising. At a minimum, I think the e-mail link should be removed.
