No it doesn't, it is to obfuscate the results about your interest and make the information they sell about you - useless. They are not giving me any money so I have no obligation to provide truthful ad clicks either.

You can't be serious, it's not comparable to DDoS attacks. It is just obfuscation, pure and simple. It is not in any way unethical either, digital surveillance that ad companies practice is on the other hand very much unethical. When I visit one website, why should dozens of third parties be able to sella and that information? When did they ask my consent? The only way to make that info useless is to have automated add-on like this, if the majority would use it, we wouldn't have as big problems of ad networks spreading malware and proving government agencies with surveillance information.
