Since when was captcha not broken? Sites like http://www.deathbycaptcha.com/user/order have been around for ages. Yes, a mere $6.95 gets you 5000 captchas solved by OCR and humans in an avg of 6 seconds. Imagine that job.
Sure, AI can break captcha, but it can be done at scale for far less than an AI research and GPU rig costs.
Google's approach to bot recognition is training their own bots incidentally, so even an adversarial network attempting to bypass it would give it a ton of training along the way to breaking in.
I don't believe it's a job. Isn't this the thing where captchas on target sites are simply mirrored on other sites like sketchy filehosts? Real human users are solving captchas to access some content hosted by this service, and the solution they enter is passed through to the target site.
I believe it is a job. There are simply too much volume to be satisfied by the inconstant traffic on filehosts. Also, they have overload and lower response times on public holidays in India.
If they are using filehosts, how would they verify captcha is correct? They can double check but it will lower their capacity and solve times.
That's also how Google self-driving cars work. When they don't understand what they are seeing they just show pictures to some random person in Google captcha who solves it quickly.
