So if I used one way to farm targeted email addresses, without the intention of selling to them but i know they are targeted to the niche. Then later once i get all the emails id just blast with an offer but not say where i got their mail from so as not to blow my cover where i got the emails form so i could keep farming them? Is this legal or not and if it isnt how naughty is it? ie likelihood to get in trouble for it? Lets say for example its form a popular social networking site i gather emails, but under the pretence of soclialising then later send offers to those emails i gathered.
