content: privacy invasion...  What privacy invasion?  it is totally voluntary!   it is all for your convenience!  and your own safety!... you wouldn't want your next door neighbor to be some creepy antisocial deviant,  or worse, a terrorist!..  and  you are totally free to opt-out of the scheme of course, at any time,  really. Good luck finding a place to rent though,  or a job for that matter (because that's coming up soon too).
