Why hiding the place of work? where’s the credibility?
 
Is just scam to get your resume info and email address to sell it later to companies as a junk .
 
Beware of the posts which send you to another site: nannies, teachers, etc, asking you to join and then they ask you to pay a fee or a discount of 30, 60 dlls. Is the same scam at single sites, they keep sending you "jobs" they have for you, but have to pay a membership to "see them".
