There are some good alternatives suggested in the attached article that 
could be used on the BAD site

For example, one could be
". . . detection services Akismet, Mollom and SBlam! all analyze 
user-submitted data and flag spam automatically. Mollom sometimes presents 
a CAPTCHA, but only when it’s unsure. But why not develop your own system 
that is tuned to the mechanics of your website?  Taking responsibility and 
removing the burden from users will improve their interactions with and 
impressions of your website. Manually moderating content is often a 
sacrifice worth making. . . . The perfect CAPTCHA is no CAPTCHA at all. "
