Yes, this is closer to what I got in mind. I don’t use Bluesky but it seems like a good idea.
What I mean exactly was some way to build a view, or a portal, of the fediverse content when we substrate what we don’t like rather than adding it. It may take the form of label or another form. I may take a form of something close to a community or a feed throught which people browsing may get rid of content that doesn’t match the view of the "portal they are surfing on.

I don’t think @Snoopy@piefed.social it has to be unique. Just like we have multiple !aww community we could have a !nodowner !positivity !nonegativity portals all living along each other present each a slightly different view of the fediverse.
