Exclusion

The user-agent string includes a reference to the website http://mappydata.net/bot/.

The referenced website confirms that the bot supports the robots exclusion text and also obeys the crawl delay.

The Mappy bot website provides details about how their robot complies with the robots.txt exclusion standard, which was described at http://www.robotstxt.org/wc/exclusion.html#robotstxt, but is not currently available. Information is available on the same website https://www.robotstxt.org/robotstxt.html and also on the w3c website at https://www.w3.org/TR/html4/appendix/notes.html#h-B.4.1.1

Details are given about preventing the robot from indexing the website but no mention about how to adjust its crawl rate.

Their advice is to include the following entry in the robots.txt file to prevent Mappy bot from visiting your site

User-agent: Mappy
Disallow: / 

No details are provided regards controlling the frequency of the Mappy bot visiting your site. You may wish to trial setting a minimum acceptable delay between consecutive requests with the following added to the robots.txt file:

User-agent: Mappy
Crawl-Delay: 10

In this example the delay has been set to 10 seconds.

As is common with website crawlers there is a delay between changes made to the robots.txt file and the change being implemented.

Take care making changes to the robots.txt file. A misunderstanding in configuration or an error in configuration can lead to important search engines excluding your website.
