Faced with stricter Internet security measures, some spammers have begun borrowing a page from corporate America’s playbook: they are outsourcing.
The going rate for solving captchas like this ranges from 80 cents to $1.20 for each 1,000, according to online exchanges.
Sophisticated spammers are paying people in India, Bangladesh, China and other developing countries to tackle the simple tests known as captchas, which ask Web users to type in a string of semiobscured characters to prove they are human beings and not spam-generating robots.
The going rate for the work ranges from 80 cents to $1.20 for each 1,000 deciphered boxes, according to online exchanges like Freelancer.com, where dozens of such projects are bid on every week.
Luis von Ahn, a computer science professor at Carnegie Mellon who was a pioneer in devising captchas, estimates that thousands of people in developing countries, primarily in Asia, are solving these puzzles for pay. Some operations appear fairly sophisticated and involve brokers and middlemen, he added.
