Video CAPTCHAs

A CAPTCHA is a challenge designed to distinguish humans from computer programs ('bots') on the internet. To be useful, a CAPTCHA must be easily solved by most humans, while being difficult to solve by computer programs. Many people have seen examples of CAPTCHAs when signing up for a free webservice.

For our video CAPTCHAs, the challenge is to provide three tags that best describe a video.

Note that you are not required to watch the entire video before pressing submit. "Stop words" (frequently occuring words such as 'and' or 'a') and duplicate words will be filtered and will not count towards the three tag requirement. After submitting your tags, you will be informed whether you have passed or failed the challenge.
