That's not quite so, Stanron. If by 'looking' you restrict yourself to a person examining them then I'd go along with you. But every record will be looked at through various analyses and automated processes without a person being actively involved, just as every credit card transaction is now subject to checks for 'abnormal activity' to try and eliminate as much fraud as possible. There are not masses of people in some benighted part of the world looking at each transaction and assessing it.

I think most people that credit card checking is A Good Thing, even though it can spot that a person placed a subscription to a porn site. But it does become problematical because the algorithms are subject to both false negatives and false positives. In the case of credit cards, the false positive is usually just your card being blocked and the inconvenience as it becomes unblocked. False positives in the Internet trails do two kinds of damage: it can trigger a full investigation into someone even who is completely innocent which is probably little more than an inconvenience. More seriously they distract resources from more worthwhile investigations.
