I'm just wondering how secure and private is clickbank, do they sell information to third party. Because there seems to be a lot of talk about click bank, and so many people are profiting from it. I was hoping to join but reluctant as you are required to post your address. Usually I avoid filling in my address in online forms unless I'm certain it's safe to do so. I'm just having some doubts about it, would it be advisable to fill the form or should I just enter something random?
