The problem isn&#x27;t advertisements per se, the problem is advertisement networks that track users and sell their profiles. The only thing I have installed that counts as an ad blocker is Ghostery. I still get served advertisements at conscientious websites like duckduckgo.com or any other place that doesn&#x27;t rely 100% on tracking networks.<p>Imagine if simply because you walked into Target, they hired a private investigator to follow you around and determine your personal habits, hobbies and other stores you visited. Imagine if they then used that information to attempt to lure you into the store, or sold that information to Best Buy so they could lure you into the store. I think most people would have a problem with such behavior. Making a more realistic physical analogy would be slipping an RFID token into your wallet without you noticing and only tracking you in stores that use the corresponding RFID reader.<p>In my opinion, tracking networks go the extra mile beyond a creepiness factor. My visit to your website isn&#x27;t tacit approval for you to peruse my browsing of other websites. I shouldn&#x27;t need to opt out of this behavior by installing Ghostery in the first place.
