etc. Most of those articles are from several years ago. The state of the art has improved since then.
- Gnolfo 16y agoSorry, I should have been clearer on what I meant. Google/etc CAPTCHAs don't work 100% against anti-CAPTCHA. As those articles suggest it's a fluctuating 80% or so, and obviously an ongoing arms race. My point was more to the fact that the slider solution wouldn't retain anywhere near the same stats if it were put up against the same level of effort and sophistication spent towards breaking it. It would get solved and then bypassed completely.
