|An example of a CAPTCHA from reCAPTCHA by Google.|
Google has a CAPTCHA called reCAPTCHA. It helps to digitize books and newspapers, believe it or not (read more here). Google also determines if an IP address is solving too many CAPTCHAs in a short amount of time, then flags that IP address. ReCAPTCHA is free and accessible to blind users. Great work, Google!

MotionCAPTCHAs are really unique.
Thanks to the advancement of HTML5, users are able to draw shapes in a box instead of squinting and turning their heads to figure out the words. This technique would be difficult for someone who has the shakes, so I think the traditional word CAPTCHAs should be offered as another option for users.
Live CAPTCHA examples:TBH Creative has included a few customized CAPTCHAs on Hickory Creek Health Care and CIRTA's websites:

I noticed a few weeks ago, Facebook is now using CAPTCHAs. My thoughts? It's about time! Spammers and bots have been on Facebook since it began. This helps to reduce those viruses and other spam posts you have seen on the social network site.
I don't think the Internet will ever be 100% safe, but every day we are learning new ways to make it a little more safe and secure!
