Craig Butler of SitPoint.com has published an article which outlines his reasoning as to why CAPTHCAS have finally reached their end of life. Captchas are usually the first lines of defense for web forms to combat against automated bots/scripts who’s sole purpose is to spam. Here is the list Craig has for why Captchas need to be replaced with something that works.
- Not A Turing Test
- All CAPTCHAS Can Be Cracked
- CAPTCHAS Are Getting More Difficult
- CAPTCHAS Measure Ability
I agree with practically every point mentioned in the article. I for one have a difficult time filling out CAPTCHAS let alone someone without sight, or hearing. At least on my blog, Akismet has been doing a great job allowing me to the keep the comment form Captcha free. I don’t know what the answer is to replace the Captcha system which is why I’ll be keeping an eye out for the follow up post which will include a set of alternatives to help spot hackers and bots without disrupting real users.
