I used to see a lot of furry accounts in the Discover feed, but I mute them when I see them, and now I rarely see them any more. I don't have anything against furries, but it's not content I'm interested in. This is more a comment that Bluesky does seem to have an algorithm (at least in the Discover feed) that is sensitive to what you do or don't show interest in. Or it could just be that a lot more people have joined recently, so the furry stuff just isn't as prevalent.
Discover has a separate "show more/less like this" button too.
Every feed on the site is its own algorithm, and most are made by third-parties. Some of the more interesting ones have fallen over and broken a little as the volume of posts has increased. The various "catch up" feeds that show the most popular recent posts give a good impression of what's happening site wide (minus any blocks/mutes).
Bluesky is trying to differentiate itself with moderation tools -- people have created lists of furry accounts so you can bulk-ignore. But yeah I haven't found my "people" there yet, most of the activity is people I wouldn't choose to interact with.
