Let’s start with an example of 3rd party monitoring: when we went to CareerBuilder. com, that is the biggest online jobs site in america, and searched for a job, CareerBuilder protected JavaScript code from 10 !different monitoring domains: Rubicon Project, AdSonar, Advertising. com, Tacoda. net all three are divisions of AOL advertising, Quantcast, Pulse 360, Undertone, AdBureau a part of Microsoft Advertising, Traffic Marketplace, and DoubleClick which is owned by Google. On other visits we’ve also seen CareerBuilder come with monitoring scripts and non JavaScript web bugs from a few other domain names.
There are pretty sound purposes to pray that if you search for a job online, that fact isn’t broadcast to dozens of agencies you’ve never heard of — but that’s accurately what’s happening here.
