Q: What's this "Federation thing?"
A: A bunch of communities, on different servers, sharing /some/ but not necessarily /all/ of their traffic. Or, in some cases, none. It depends.
The User Guide has a good section:
@hanung665 You'd have to get out-of-band verification, or a specific denial.
There was a profile claiming to be a co-founder of Mastodon yesterday. It looked and smelled funny, I did some investigation. Eventually Gargron made a statement that there was no such thing.
The account's toots started disappearing, and someone claimed that it had been stolen from him (or copied, not sure which).
It becomes a test of truth -- consistency and correspondence are strong tip-offs.
@hanung665 Wikipedia's Criteria of Truth page lists various tests, some better than others.
"[T[here seem to be only three functional, effective tests of truth[:] correspondence, coherence and pragmatic."
"Pragmatic" is "is the knowledge useful in application?"
"Correspondence" is "does the knowledge correspond with that it describes?"
"Coherence" is "are all pertinent facts arranged in a consistent and cohesive fashion as an integrated whole?"
@hanung665 There's also the consistency tests: do the claims not contradict one another, and relate in a logical fashion. You might consider this a /rational/ test of truth. It's useful, but incomplete. Often it's all we have to go on, though, and it can be leveraged in useful ways.
Generalistic and moderated instance.
