Based in Pakistan, apparently. (That one wasn't captcha'd.) I think we could both be right - I'm watching a video from a Google session about captchas which does suggest the bouncing method you hinted at.

I haven't seen much that suggests that OCR is being seriously used by spammers yet (although it's probably only a matter of time). The IP address shows that the computer that posted the CAPTCHA results to you is (almost certainly) in India. But that could easily just be a server that's hosting the code, and the person typing in the CAPTCHA details could be elsewhere. For example, I'm typing this in the UK, but the computer it's going to be posted to is in the US. Pretty tricky to tell one way or the other though.

Which makes me think it's almost certainly a human. It could have been a fake, or an OCR, but I've also seen attempted (or real) registrations from .in in the past couple of days - so I'm sticking with my hypothesis for now.
