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).
If so, you're probably looking for the "show less of this" feature rather than muting?
(Not that it’s a guarantee of anything; notably, SecondLife is essentially _only_ furries.)
I'm pretty sure most "normal" people would react in a similar fashion, which kind of makes this a notable catch-22 for wider Mastadon-adaption.
