My comments are littered with folks asking "why is it a problem if your blocklist is public on Bluesky?"

I'm glad you asked.

"Who you block" is a reasonable indicator of your personal alignments. If you block TERFs, you're likely trans-friendly, if not trans yourself. If you block white supremacists, you're likely in support of multiculturalism.

If you block government entities, well, you know how this goes.

Do I trust Bluesky to handle that information with care? Hell no.

@vkc And if it's public, it's not handled with care.

@niko @vkc I mean...

It's not.

What you post to your PDS is public. The updates to it go to the "firehose", which is this public stream of updates. App views then take that information and filter it and crap. There's some other stuff going on here but this is pretty much it.

So your block list is a request to these views to not show your public posts to certain people.

If you are expecting more than that you are quite mistaken.

Don't put sensitive info on social media.

@crazyeddie @vkc Even a block list can tell a lot. It's not just about what you don't want others to see, but also what you don't want to see yourself.

@niko @vkc If you just don't want to see it then that's what mute is for. It's possible to provide that feature without it being public and it apparently does that in bluesky.

Mastodon does the very same thing. Mute is just for you. Block also informs the user and won't let them see what you post. This is at least partially public because servers have to know to do this for you. If you are on an openly federating server then you are probably exposed here.

Were you properly informed?

@crazyeddie @niko a big difference here is that on Fedi, the block informs *your server* and *the other server*, but on Bluesky, it informs *everyone* because it's centralized.

An end user has to be pretty smart to exploit that via Mastodon, and it'll be incomplete because of federation/defederation. On Bluesky, it's trivial and complete.

@vkc @crazyeddie @niko A quick clarifying question; do you mean actual blocklists or simply who you have blocked? Because on BlueSky those are two different things
(For anyone who doesn’t know I’ll explain below)
If I make a block list on BS & start adding people to it, that’s easily accessible and trivially available

If I simply block someone, that information is NOT trivially available, much the same as fedi; you CAN find it but you have to know how.

Block lists are meant to be shared (IIRC)

@vkc @crazyeddie @niko To be clear, I think Mastodon and BlueSky both have massive problems that need to be fixed, but they both have some promise; I like BlueSkys approach to account portability and better anti-abuse controls and I like Mastodon/fedi approach to distribution.

hopefully, both of them will fix their problems. It would be great to have multiple alternatives talking to each other other.
