Facts are facts, in the same way rocks are rocks. You can gather them from anywhere they exist. There might be places where it is easier to gather facts than Reddit. But wherever you get purported facts, it's hard to know whether they are merely claims, or actual facts. Most of us do indeed short-circuit our evaluation of claims when we trust the source, and although this sometimes causes us to wrongly believe false claims are facts, I think it's probably a good optimization on balance. Nevertheless, "who should we believe?" remains one of the most fundamental questions of human existence. The tremendous energy required to confirm the factuality of even a trivial claim makes me agree with what I think is your premise — the quoted poster was making a highly dubious assertion of "facts". But I think s/facts/claims/ would suffice to fix it.
