Interesting to note that a site like this could implement a rather dark and exploitive business model: 1. Service A lets a user pose a captcha to a target 2. Service B sells captcha solving service to bots, using service A as the solver backend 3. A service A user may become a victim of a bot that uses service B An interesting feature is that it can sell a single captcha solution to multiple bots. Let's call that the captcha multiplier (CM). Here the CM is 3, since the challenge is reused 3 times: 1. Bot X encounters challenge 1 2. Bot X poses challenge 1 to service B 3. Service A poses challenge 1 to bot Y 4. Bot Y poses challenge 1 to service B 5. Service A poses challenge 1 to person Z 6. Person Z solves challenge 1 7. Bots X, Y get solution 1, pay service B Here is what CM=10 looks like: 1. 100 humans use service A 2. 90 bots use service B 3. Only 10 actual humans solve captchas This woylr a captcha multiplier rate of 10.
