What I want to know is: who actually pays any attention to these spam posts so that it's worthwhile enough for them to do it in the first place? There are so many nowadays that it's just ridiculous.
A preponderance of Google's business strategy is selling advertising. I'm of the opinion that at some point, the point of diminishing, or no returns on an advertising dollar has to be reached.
Conclusion? people who advertise have no sales resistance to the people who sell advertising opportunities. They buy into the created fantasy of enormous ROI. Advertising can obviously work, and work well. However, it likely only does so for the people, (read "large corporations"), at the top of the pyramid, (scheme). It has to eventually come to a point where there are more advertisers than potential customers.
A lot of these internet "Groupon" type promotions have good market penetration, but turn out poorly for small business owners. In these cases, if the deal is really good, you'll get plenty of responses, but run the risk of bankrupting your business in the process
More money is likely made selling advertising opportunities for male enhancement pills, than selling the pills themselves. Although with that said, the male ego is a wallet of opportunity ripe for the picking.
All of that notwithstanding, given the low cost and ease of sending an email, I imagine that spammers expect to send out 100,000 emails, to justify pulling off one really lucrative identity theft.
The spam that this site gets, "earn a million dollars working out of your bedroom", is obvious social engineering enticement. I just don't have the nerves required to follow these cookie trails, to be able to gauge the extent of what the ripoff would be......(wait for it)......Ladies first maybe?
