The DuckDuckGo 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

Their advice is to include the following entry in the robots.txt file to prevent DuckDuckGo-Favicons-Bot from visiting your site
User-agent: DuckDuckGo-Favicons-Bot Disallow: /
Or maybe try with reference to their main robot
User-agent: DuckDuckBot Disallow: /
Also to control the frequency of DuckDuckGo-Favicons-Bot 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: DuckDuckGo-Favicons-Bot Crawl-Delay: 10
Or maybe try with reference to their main robot
User-agent: DuckDuckBot 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.
