According to a study released by the Messaging Anti-Abuse Working Group (MAAWG), 52% of computer users said that they have clicked on a spam e-mail.
Why? Seventeen percent said that they made a mistake, 12% said that they were interested in the product or service being offered, 13% said they simply had no idea why they did it, and another 6% "wanted to see what would happen."
Even though only a small percentage of computer users actually click on spam to try and purchase something, it remains profitable, as over 94% of email is spam, according to The New York Times.
