Spam gets 1 response per 12,500,000 emails: A team of reseachers became spammers to measure response rates (is there an ethical issue there?).
Using ‘proxy bots’ the team of researchers managed to control 75,869 hijacked machines to conduct their own fake spam campaigns.
The researchers used two of the most popular ploys currently used by spammers – firstly offering a fake pharmacy site and, secondly, offering a herbal Viagra-style remedy to boost libido.
“After 26 days, and almost 350 million email messages, only 28 sales resulted,” says the research paper.
