40.2 Minimum Methodology
- Bluesky real-time: subscribe to the firehose with a keyword/user filter. For historical data, Bluesky has no native search API — use third-party (Reaper Social).
- Mastodon: each instance has its own API. Federated search is limited. List instances relevant to the target (e.g.
infosec.exchange,mas.to). - Nostr: NIP-05 verification exposes domain-linked identity. Allows pivoting from handle to verified domain.
- Farcaster: Warpcast is the main client. Public API for feeds.
40.3 Use Cases
- Extremism monitoring: migration of accounts banned from X to Mastodon / Nostr.
- Geopolitical investigations: Russian / Chinese actors moving to decentralized platforms after blocks on Western ones.
- Crypto communities: many Web3 projects use Farcaster and Nostr natively.
