Weird, DDG supposedly uses Bing which should be indexing everything. Then again this is Microsoft, who can't even get local search working - Win11 lately can't even find Add/Remove Programs on my PC, I have to go through Settings and click 18 times before I find it.

re blocking: after every search in the upper-right corner of each link I see 3 dots which opens a menu and offers "block this site from all results".
