Even the Ad Industry Doesn't Know Who's Tracking You
jfruh writes "The Internet advertising industry is keen to stave off government privacy rules and opt-in-only browsers by loudly proclaiming its adherence to a self-imposed code of conduct. Yet a little digging shows that even "self-regulated" advertisers link to services that link to other services that nobody's really sure what they do. That's why, for instance, when you visit a page on the Sears website, your web browsing behavior is being collected by a company that sells ringtones and won't return emails asking about their privacy policy."

The NoScript list of blocked domains on many (even legitimate) websites is scary indeed. One of my favorites is Javascript from ru4.com required to be able login into your banking account on chase.com. Based on the name, it looks like a phishing website to me...
It lets the sites set their cookies, waits a few seconds (or until tab is closed), then nukes 'em. There's a whitelist for sites you actually use.

I like this solution because you don't have to wait for Ghostery to add support for an advertiser, or an updated filter definition for adblock. EVERYTHING gets nuked, except the sites you care enough about to whitelist. It's a better default cookie policy.
I built a script to generate a graph of third-party resources a web page loads, which often represent advertising and tracking (sample output for Spiegel Online, a German newspaper).
I also wrote a blog post about how advertising and tracking make sites slow (in German) that contains even more graphs from when I ran the script in January 2013.
