Network Account Management | Bluesky

Accounts in the atproto network are app-neutral: a single account can be used for short posts, long-form blogging, events, and more. But until now, the best way for users to create and manage accounts...

An upstream network problem has been impacting almost all Bluesky network services for the past 3-4 hours. Posting and other public interactions are disrupted for many accounts.

As connectivity recovers, the firehose and other services will see large surges of events.

Moderation is a crucial aspect of social networks. However, traditional moderation systems leave communities vulnerable to sudden policy changes and mismanagement.

To build a better social media ecosystem, it's necessary to try new approaches.
