Why are there a million websites that scrap and republish stack overflow content? SEO induced page hits for fraudulent publicity?
Whatever the reason I hate them so much.

Use DDG and thank the
!stackoverflow bang

As I started using DuckDuckGo, I felt more productive. No fucking coderoad dot ru with poorly translated copypasta anymore.

less popular search engine might be better here as nobody tries SEO for DuckDuckGo.

I guess it is about showing ads. StackOverflow content brings page views and the impression-based ad business still exists.

So as always: Your web experience is worse than it could be because of ads - even while you don't actually see them because of having uBlock Origin installed.

probably for the same reason why 10 years ago i had a contract for a bot that would regularly scrape a list of blogs, take their new articles, change the wording and paragraph order a bit, and then republish them on the client's wordpress site...
