The social graph, at least in Bluesky's own collection[0], is made up of the sum of follow records in individual repositories on PDSes. Anyone can enumerate them. [0] A collection is basically an app's particular set of records stored in a user's PDS repository. Here's an example using the Bluesky CTO's follow records: https://pdsls.dev/at://did:plc:ragtjsm2j2vknwkz3zp4oxrd/app.bsky.graph.follow https://pdsls.dev/at://did:plc:ragtjsm2j2vknwkz3zp4oxrd/app.... These are summed up by Bluesky's app server (app view) and then used to fill out following lists in apps that connect to that server through its API. A fact checking or web of trust tool could pull these records down and use it for exactly this purpose. It could even weight by who they repost, for example.
