More importantly than the technical issues, CAPTCHA completion is already big business. Where the common scripts are known to fail, malware developers just feed the CAPTCHAs over to call centres in Africa or somewhere else cheap.
Everyone wants CAPTCHAs that minimise the annoyance to end users, and that are hard for a machine to crack. But the above business model means that, as a service designer, you either need to accept some degree of CAPTCHA fail, or somehow not annoy your valid users whilst also make solving them take unprofitably long for a remote worker to do.
- munger 13y agoYeah this. SEO/internet marketers who want to go create a bunch of spammy backlinks through user profiles / blog comments on forum sites and blogs (anything that allows account creation and user generated content) to target affiliate marketing sites they own have pretty great automated tools to do this that integrate with the commercial captcha solving services. The captcha solving aspect is around $1 - $1.50 per 1000. You can't really prevent this and it really doesn't matter how effective the captcha is because outsourcing the human required to solve it is so ridiculously cheap.
