DDG would be a lot better if lite.duckduckgo.com didn't automatically block anyone who looks deeper than 200 search results as a bot and then force a JS only challenge on the lite page (that crashes old browsers). I think this false positive could be solved by DDG lite returning more than 10 results per page.
Huh. Didn't know there were 2 non-JS interfaces. I get redirected to https://html.duckduckgo.com/html/ (which is also 10 per page).
I do appreciate that DDG has it at all. Google blocks all non-JS searches these days.
I've never noticed the challenge, but then, I don't think I've ever clicked 20 pages into the search results either. Usually if I've clicked on a couple of pages I feel it's time to refine my query..
