only thing I can think of to block the scammers on this site would be for Rick/the webmaster to write a "robots.txt" file and tell the search engines what they can and can't index. That would only keep search engines from seeing the classifieds or other "off limits" sections, but not a person from coming to see the page. On the sites that I run, I specifically exclude pages with classifieds or names/email/phone info.
