An app that intercepts the personal data that I generate and allows me to dictate what the computer transmits, for instance I could tell it to say that I am a poor 20-year old white woman and then advertisers who target on that stuff would more likely advertise stuff to me that I genuinely couldn't care about if I tried to. This would waste their time and money and cause me to giggle when I see an ad for something very girly knowing that the me they think they're selling to isn't real.
