Understanding Bluesky's AT Protocol Privacy Model
Bluesky uses the AT Protocol, a federated system where your data is stored on Personal Data Servers (PDS). Unlike centralized platforms, this means your posts and interactions are distributed across multiple servers. While this offers portability, it also means your public posts are widely replicated and harder to fully delete. Choose your PDS provider carefully, as they have access to your account data. Self-hosting your PDS gives you the most control but requires technical expertise.
