Exclusion
The user-agent string includes a reference to the website http://gumgum.com.
The referenced website confirms that the bot supports the robots exclusion text and also obeys the crawl delay.
The GumGum 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 both preventing the robot from indexing the website and how to adjust its crawl rate.
Their advice is to include the following entry in the robots.txt file to prevent GumGum from visiting your site
User-agent: GumGum Disallow: /
Also to control the frequency of GumGum visiting your site, setting a minimum acceptable delay between consecutive requests can be set with the following added to the robots.txt file:
User-agent: GumGum Crawl-Delay: 10
In this example, taken from their website 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.
