It's pretty simple really, and it has nothing to do with your stored cookies etc either. While disallowing scripts to run can keep you from having to
look at them over and over, it still comes down to your IP getting logged by an ad server.
The reason I know this, is because a couple years ago, my ISP went down for a few days, so I "borrowed" my neighbors wireless. I gave myself an IP,
used my preferred DNS and went about getting my internet fix.
First I checked out the weather on intellicast, and visited a few other sites that had ads all over them. (On that comp, I only had a Windows OS
installed and was using IE7, not that there's any relevance there.) I also had a freshly cleared cache.
On each and every site I visited, the ads getting pumped to my browser were for DUI attorneys! At least 6 of the sites in a row had the same targeted
advertising. Yes, my neighbor had gotten a DUI and was looking for affordable representation.
While I never did any kind of searching for such a service, my neighbor did. Since his IP remained the same, any script calling up an ad from that
particular advertising service, got served targeted spam from subset X.. DUI attorneys.
