Since DetoxBox is all about fighting spam on your GMail page, I figured that GMail ads would be the best place to advertise it. And I was right: I have added "Black Friday" as keywords and placed a GMail ad, choosing "Health & Fitness Buffs, Lifestyles & Hobbies" as my target audience, and got 216 impressions and 171 clicks (81% CTR) before they banned my ad for "Malicious software".
Now, the landing page was rather sketchy, I admit, I've made a better one using Umso since then, so I'm trying it again, hope this time it won't be banned.
