If you are not careful it is easy to find a lot of difficulties in the ethics of marketing. For instance if you deal with a direct mail list broker you might find your own name and information on the list that he sells you. It is one thing to buy the names of some faceless potential buyer, perhaps you would see nothing ethically wrong with that and as you are in a position where you have to sell to survive that sort of thing takes a secondary place in the heart and the mind. Then when you realize this person is selling your name and you mailing address you do not quite feel as laissez faire about the entire thing. For me the big thing would be my gmail account. I could care less about my other email addresses in all honesty.
