Yeah, it is. Give people better interfaces for controlling the sources. Set a higher bar for quality before even letting a site put their articles up.
It wasn’t a problem on Google News for years and it’s because it didn’t pull articles from those sites. A super easy solution is just dump all those newer contributing sites.
Saying that Google has problems with spammers in search results too isn’t proof that the problem is hard to solve, because it used to be solved pretty well in both cases. It’s proof that Google has de-prioritized solving it.
