Huh? I wonder if this is a particular client's settings or something. I see generally what hashtags I search for, people I choose to follow, and often expand it to people who follow me, and people those I follow choose to follow.

Some of that will have the effect you mention, which I'm aware of when I search for it (as sometimes, I WANT to see the pulse of the "main channel" as it were. But hashtags seem not to be sorted on Coracle anyway other than by most recent -- I see what I search for, without any editorializing.

On twitter, on the other hand, if I search by a hashtag, the results are sorted based on their algorithm, rather than most recent. This is where shadowbanning comes into play. To the best of my knowledge, no client currently does this, and the network itself certainly doesn't.
