Back when I was on reddit, I subscribed to about 120 subreddits. Starting a couple years ago though, I noticed that my front page really only showed content for 15-20 subreddits at a time and it was heavily weighted towards recent visits and interactions.
For example, if I hadn't visited r/3DPrinting in a couple weeks, it slowly faded from my front page until it disappeared all together. It was so bad that I ended up writing a browser automation script to visit all 120 of my subreddits at night and click the top link. This ended up giving me a more balanced front page that mixed in all of my subreddits and interests.
My point is these algorithms are fucking toxic. They're focused 100% on increasing time on page and interaction with zero consideration for side effects. I would love to see social media algorithms required by law to be open source. We have a public interest in knowing how we're being manipulated.
I get these texts occasionally. What's their goal? Ask for money eventually?
