Mastodon has no algorithm, if one guy posts 30 things you get them sequentially so it is dominated by who types the most until they eventually annoy you enough to unfollow them. No algorithm also means you don't filter out their meal photos etc. based on clicking not interested.

Twitter is maybe even worse now though, no matter how many times you click not interested on hard right content, street fights, etc. it just forces it on you. They have stop letting you adjust aspects of your feed.
