I had consulted Professor Google while planning a trip.
Shortly afterwards I was on Facebook and among the posts from friends were advertisements for accommodation and things to do at the location I’d Googled.
If Facebook and Google have algorithms that can do that, surely they can have algorithms to monitor, and act on, posts like those of the gunman who allegedly killed 50 people in Christchurch, which ought to have raised multiple red flags.
If they can monitor to sell, why not monitor to secure?
If it’s not invading our privacy to match our searches with sellers, it can’t be invading privacy to monitor searches for security alerts.
Targeted advertising makes money, monitoring for danger won’t but it should be part of these companies’ social responsibility.
