Source?
How do you define reliable?
Why is the authors identity important?
Facts don't change because you know the authors name, or trust the source, or like the person telling lies.
The idea that anonymous sources, or "untrusted" sources (for someones definition of trusted) cannot be the source of facts is gaining ground right now, and it needs to be pushed back on wherever it is seen.
It's a lazy Ad hominem, and it's down right dangerous.
I don't care if it's elected officials claiming Russian malinformation or a random chess thread, this is the hill I choose to die on.
