As everyone knows, one of the main differences between Bluesky and even "old Twitter" is the blocking culture. One of my favorite stories from when I first joined Bluesky came in the wake of a series of negative interactions with a semi-prominent journalist figure. I considered blocking her but then I thought "no -- while this wasn't pleasant, there was nothing abusive here, so I'm going to be better than that." The next morning I woke up and discovered ... she had blocked me! Moral of the story: block first. At least that way you get the satisfaction.
The block-happy culture of Bluesky has led to a lot of chatter about Bluesky turning into an "echo chamber" -- an accusation which, ironically enough, is one of the fastest ways to get yourself blocked on Bluesky. For my part, I think the echo chamber complaint is overblown (in part because very often what we tell ourselves is "exposure to diverse views" actually is a way to reaffirm "wow, those people are maniacs"). But I do think that it is important to start thinking about best blocking practices in a informational system where "block early, block often" is normal and not frowned upon.
Take block lists, for example. These can be valuable tools to ramp up blocking of entire suites of bad actors quickly. But they're also easily abused. I've seen reports of trolls and other bad actors setting up block lists seeded with an assortment of the "usual suspect" controversial accounts and then, once people adopt them, adding in (say) trans rights activists. If you're not paying attention to who is curating the lists, it is easy to get taken in by that sort of move. That doesn't mean "don't use block lists", it just means be mindful when and how you use them. The mantra of "block early, block often" shouldn't be used to disavow one's own responsibility over the choices you make -- rather, it should accentuate it.
A similar concern attaches to "secondary" block lists -- that is, those populated not by the primary bad actors, but by people who follow those bad accounts. Again, it's not that I can't see the use case for these, but they're fraught with danger. Most obviously, people who research, say, antisemitism (to use a random example) may follow all sorts of unlovely accounts for research and monitoring purposes. Follows do not equal endorsement. And the broader version of that insight is that who people follow is their business. People make follow/unfollow decisions for an infinite number of reasons. We have absolute autonomy over what shows up on our feed, but we shouldn't start claiming authority over other people's feeds. If they start being unpleasant in their own voice, block them, but the moralization over who one follows strikes me as problematic. Tend to one's own garden.
Maybe you have quarrels with either of the above examples. But the bigger picture point I'm trying to make is this: a social media culture in which blocking is normal also has to be one where we take responsibility for the choices we make when blocking. A social media culture where blocking is rare can get away with people being less mindful about it, because they're only going to be acting in the most clear-cut cases -- one doesn't need to do a lot of deep reflecting to justify blocking RandoNazi1488. It's when we move beyond those cases that thought and consideration becomes important. And precisely because there are not and cannot be rules about blocking -- it is, ultimately, a matter of personal discretion -- it is especially important to cultivate a suite of good virtues around blocking. Block people who are abusive, but not people who just disagree. Block people for what they write, not for what the people they follow write. I don't think these are especially onerous, and I think most people are trying to follow them to one degree or another. But it can be easy to conflate Bluesky's quite healthy "block early, block often" mantra into an unhealthy belief that the actual ethos of the community is "I shouldn't have to think at all about my blocking choices." That isn't our ethos, and it shouldn't be our ethos.
A willingness to block often is not the same thing as being cavalier about blocking. Ideally, a healthy blocking culture will entail thinking carefully about how to balance hearing from a range of views and avoiding epistemic silencing with having a pleasant experience and not being inundated with worthless troll blather. I do think most people are capable of striking that balance in a reasonable way, but it isn't something one can do thoughtlessly. With great blocking power comes great blocking responsibility, and that's something we should embrace.
