Breitbart. Plandemic. It was removed but no penalties were leveraged.

If I were a Facebook employee with typical bay area California politics I'd just selectively apply my bias and be over zealous with the fact checking when I find something is being shared amongst folks who are being swayed to the Republican side

As long as I get to decide this, I can ensure that my bias controls the narrative to whatever extent I can

Recently I saw a story alleging mailboxes were being taken away in a conspiracy to manipulate the election. All the facts are true but they can be assembled to fit this kind of conspiratorial narrative, which is weak because tend of thousands of mailboxes are moved all the time.

You could rate this "unproven" if you were being consistent but it doesn't help Democrats so why would you?

As long as people are in charge of these things it's never going to be fair and they'll always have the power to influence swing voters.
