To be fair, Bluesky does have “blocklists” maintained by other users that you can opt into, and quite a few popular ones exist with active maintainers who take and act on reports pretty quickly. So you still can delegate moderation responsibilities. One advantage to this is that you can opt into a few blocklists based on what you personally want to block - separate lists exist for hateful bigots, crypto pushers, and so on. I gave it a shot out of curiosity and haven’t run into any issues yet, but that’s just me.
I still prefer Mastodon for broader AP integration, and I think blocklists aren’t discoverable enough outside of word of mouth, but I am curious to see how that turns out for Bluesky. Certainly an improvement over Xitter imo.
