Bluesky Social Network and Starter Pack Dataset from October 2025

Encompassing the Bluesky following network and starter pack network data from late October 2025. It includes anonymized user identifiers and starter pack information for computational network analysis.

Use Cases

• Analyze the structure of the directed following network using anonymized user identifiers.
• Study the influence of starter packs on network formation by examining relationships between starter pack creators and members.
• Model the propagation of follows through starter packs using hashed identifiers for users and packs.
• Investigate the curation patterns of starter packs, which contain between 6 and 150 users per pack.

Strengths

• Data represents a large-scale snapshot of the Bluesky social network from a specific point in time (late October 2025).
• User and starter pack identifiers are anonymized using a non-reversible hash function for privacy.
• Includes both pairwise following relationships and higher-order network data from user-curated starter packs.
• Starter packs provide curated user lists with a defined size range of 6 to 150 members.

Limitations

• The dataset is a static snapshot and does not capture network dynamics over time.
• Anonymization prevents linking data to real-world user identities or external datasets.
• The specific size of the dataset in terms of rows, columns, or file size is unknown.
