Good luck finding mine, For some unknown reason they keep sending me commercials offers and infos from Brazil, and I am not in Brazil nor do I visit webpages in Brazil or even search info or content from brazil, they are not sure where I´m from so they keep trying and keep failling. As long as you keep cleaning your browser and cookies and and all that mambojambo stuff you will be relatively safe, and unrequested emails that says "we cannot be considered spam because we give you the option to unsubscribe our mail list", well to you I say SPAM, I say this because I have this option given to me from my right of freedom of speech and freedom of choice.
A question aside, couldn´t this be considered some sort of harassment? Think about it, this guys are selling our info to a 3rd party without our consent, and that 3rd party send us annoying messages all the time. MMmmmm just wondering
