"HT4K" is a value found in Public Key servers, and is used as a lightweight deterrant to 'spam-bots'. By making the verification code field required, and naming it 'captcha', most spam-bots will read the form code page, and just keep moving along to find a totally unprotected web form to submit spam.

CAPTCHA stands for �Completely Automated Public Turing Test to Tell Computers and Humans Apart.�
