User-agent: adidxbot
Disallow: /To allow it, use Allow instead of Disallow. Before blocking, weigh what it brings: look at how often it visits and what it brings before deciding.
How do I see whether AdIdxBot visits my site?

Anyone can copy the name in a user agent, so counting log lines is not enough. Knocklog reads your site's traffic on any host, confirms who is who, and shows how often AdIdxBot came, which pages it read and what that brought you.
How do I know it is really AdIdxBot?
