Or to prohibit all robots including Cole8Spider, add:
User-agent: *
Disallow: /
To achieve the latter without editing the robots.txt file, add the following meta tag to your page:
<meta name="robots" content="noindex,nofollow">
When Cole8Spider sees any of the above, it will not proceed any further with your site.
