My website has a referral program..I have a page called refer a friend. Logged in users can enter their friend's email addresses. As of now my site doesn't have any email limit. Now my question is Will I get any legal problem, if the user submits spidered email address to earn referral money?And how exactly big sites handle this problem? Can I use mailchimp api for this?
