Right. I'm just saying that in the end there is no way to protect against using a real human being to defeat a captchas. I've even heard of porn sites requiring users to crack a cpatcha to get in, which they then resell to spammers as a revenue stream. Hard to protect your site against nefarious means like that.

The latest response from a recent article I read is to use people in

countries to do many many multiple of manual sign ups for $3 a day.

Sadly this also overcomes alternative approaches such as providing an
