Oh believe me, I know. DDG was the first one I tried, and I tested it with every configuration possible. Like many other search engines such as startpage and kagi, you sure can do this in the settings, but it will do absolutely nothing to stop it from using your IP address to net locationally biased results specific to your current location. You may assume it would function like this, but it doesn't.

I even tried their html and lite versions, but although it was less cluttered and much more pleasant to use, it still provided results that were very clearly based on my IP address.

I'm not even sure what those settings do because they appear to have no function. Maybe they change language and currency on some sites for convenience, but again, that's not what I'm talking about in my comment! I'm saying a search engine should not use any locational data whatsoever to adjust results. And if you reply "well, good luck finding one because it doesn't exist," then congratulations, you understand my comment! They don't exist because we've all sacrificed our societal wellbeing for the sake of the smallest convenience.

Even if changing it to another country/region worked (it doesn't), we'd still have the problem of netting biased results based on what country I switch it to. That would be akin to searching while using my VPN, which once again, does not solve the problem of search engines using IP address to provide locationally biased results.
