I really like the DuckDuckGo search engine and what it stands for. I do have an adblocker installed. The single advertisement next to the DDG search window, I keep blocked, even though I have nothing against giving you back a little revenue for this amazing thing I can use.
However, your ads are rotated through Bing. I do not trust Microsoft. As far as I can see, these ads, just like most others on the web, are able to track potential identifying information to the advertiser, as well as to Microsoft.
This is of course 'neccesary' if advertisements are used in a CPV-model (cost per view, or cost per million views) since you need to know when the ad is seen or not.
I would really appreciate it if DuckDuckGo started providing their own advertisement service, which has the following features:
-Advertisements are loaded as an image, from the DDG servers (no requests to the advertisemers website is made, so they cannot track your IP, browser settings, referer, etc).
-Advertisements are loaded as an image, and not as a flash applet. (Flash has rules of its own, which normal browser settings cannot prevent against)
-Advertisements are paid through a pay-per-click (or pay-per-purchase) model, to ensure that no data needs to be sent to validate the ad cost.
If this would happen, I would be very happy. And I would also gladly open up a spot in my AdBlocker for it.
