At this point, Instagram decided it wants to be a TV and just show me what it wants me to see, not my carefully curated feed. I'm letting my account die.
I’d carefully curated my feed to what I was interested in, following a load of really good abstract and generative artists, until it would suddenly decide that what I really wanted to see was nailcare tips or whatever.
After a few days of me actively pruning content the feed would settle down, but it happened more and more frequently until I couldn’t be bothered anymore.
