CAPTCHA
From HostBaby Wiki
A CAPTCHA or Captcha (pronounced /ˈkæptʃə/) is a type of challenge-response test that keeps spam robots from posting spam on your guestbook. It requires a little code to be entered that only a human being can reproduce.
Once you publish your site in Hostbaby2 you will see the Captcha code on your Guestbook page.
