I don't put my religion on my CV and would not
want any prospective employer knowing about it - not because I'm ashamed about it,
just that it's private information which isn't relevant to how good (or otherwise)
a job I'll do.
That's the point. Giving them your usernames and passwords to places
like Facebook, dating sites, etc., would give them a way to find out
information they normally wouldn't.
