I've often seen, that when you click on a sponsored link in DDG Ghostery blocks the site saying "Ghostery prevented a redirect from
r.duckduckgo.com to <some site>, which is part of <some tracker>". Is this necessary in some way? Could you prevent it? In the end DDG is a privacy-focused search engine and maybe tracking sponsored ads (although not directly provided by DDG) shouldn't appear there.
Example: first ad on this page
