Facts are things that actually happened, (knowledge of) facts can be gathered from Reddit threads but so can (knowledge of) bullshit that is erroneously thought to be facts.

on edit: note I do not say anything about verification, as that is a different thing as to whether or not a thing is a fact. Verification is about how sure the knowledge we have is a fact, but whether a fact is verified or not it remains a fact even if we do not know it is a fact.
