you want to bulk solve captcha's, in a non nefarious manner? but do you realize that bulk solving is nefarious? captcha is to prove you are human, not a bot or script.
Except for the fact that humans are solving them, only getting paid for solving them and rendering said captchas effectively redundant. The key term here is isolation, where rather than captchas serving to hurt flow states, they are isolated away and offloaded more comfortably to the solvers who are happy to solve them in return for a reasonable fee. Google's new system is a bit more robust however and uses fingerprinting. One could argue that fingerprinting is more nefarious than letting people have a small income from captcha solving.

you think the fact that humans solving them in an automated fashion, instead of a computer doing it, is what makes all the difference? Rendering the capthas redundant is the problem.
Maybe you just need an app that signs you up for sites.
