The other HH's forum has also been getting spambot registrations, but so far none of them has been able to post anything. There is a way to prevent bots from accessing a site by editing the robots.txt file, but I would need to know what server they are operating from.
If you were to be the victim of such a problem robot, or simply wanted to disable robots from including a portion of your site in there search engine, you can create a text file called robots.txt and place it in the root of your website (like
http://yoursite.com/robots.txt). Within that you can block a specific robot or a specific location. An example makes this easy to understand:
# robots.txt for
http://yoursite.com/ User-agent: *
Disallow: /privatejournal
Disallow: /temp
User-agent: Teoma
Disallow: /
This robots.txt would disallow any robots from indexing any files in
http://yoursite.com/privatejournal and
http://yoursite.com/temp and disallow Ask Jeeves from indexing the site at all.
