AFAIK, two people with the same three IP octects being two unique people would be 1 in 1 million chances so I assume I can be rest assured it's someone's bought trying to scrape my pages.

This is an invalid assumption. Any two people from the same ISP (AOL, Time Warner, etc.) will be quite likely to have the same first three octets in their IP. I'm not sure why you're trying to determine if two people from the same IP-block are on your site at the same time - this seems unrelated to bots scanning your site.

Instead, I think you should look into more generic rate-limiting techniques. For example, if you're using CGI::Application you can use CGI::Application::Plugin::RateLimit to limit how fast people can access your site.
