In the last couple of weeks, on my Android phone, I've noticed a lot more alt-right fake news stories showing up on my Google Now screen. (Screen to the left of home with local weather, time-to-home, news I'd be interested in, where I parked my car.)
It's always been a creepy dance as Google Now learns what it thinks I'd be interested in, and digs for stuff to show me and keeps track of my reaction. Invasive as hell, but it does a really good job. sigh
You can directly tell it that you're interested in certain subjects, not interested, or block entire sites. Sites like InfoWars and Breitbart were blocked in the beginning. A few flat earth / moon landing hoax sites got blocked along the way. (I'm interested in space topics.)
Just in the last couple of weeks, I've noticed a real surge in stories from alt-right fake news sites. (block-block-block...) This might be due to Google trying to adjust to what it thinks I want, or it could be that someone in the alt-right shadows, like Cambridge Analytica (Bannon / Mercer), has worked out how to game Google's analysis of sites and articles and are trying to crap-flood the system, especially to phones tuned to their dog whistle.
I'm mentioning this here in case anyone else has noticed this, or can look for it in their experience. Meanwhile I'll see if I can find out more about how Google Now selects stories. (I admit that I'd probably use that knowledge to boost Scientology-critical stories. )
