You need to curate your algorithm. Took me 10 years before I started blocking aggressively and now my feed is amazing with 90% bangers. Twitter is by far the best product in this space. Every other platform is 2+ weeks behind. Twitter is where the news breaks.

I had a well curated feed too (even used word filters) and yet I felt compelled to pack up and walk away. It was simply not enough.

The negative effect the various drivel had on me was nonlinear. Even if 99% of posts were fine, if that 1% was seriously upsetting, it just ruined the whole thing.
