I know that some affiliate networks like Maxbounty and others have a large number of email submit and free download offers. As you may have experienced, most of the free download programs are trojans that hijack the users' systems. The email submits are nothing but email address harvesters to send spam. Is it worth to promote offers like this or do you believe that they will result in low click through rates or users not revisiting your site? Of course the affiliate network does not care whose property they destroy, but what about you? Do you think that bad ad experiences will cause your visitors not to return?
