Exactly. This is exactly why systems like this pose such a threat. And what about the few that decide to say "Fuck the system!", well they become a social underclass - they can't get loans, mortgages, jobs, etc. It's a very slippery slope. Everyone should be entitled to a private life. And not everybody's private life would chime well with 'the establishment'. I could imagine myself falling foul of this because I produce music. It wouldn't take long on my facebook page to see that, so if a landlord could mine that information then I'd be unlikely to get a tenancy based on my potential to be a nuisance to my neighbours.
