Leave it up to the courts to decide. It seems to be the only place that the truth matters now.

If you cannot reasonably prove you acted in good faith - or cannot prove you did not knowingly make false statements it’s (and now that they are proved false you retract and remove) then you are a problem.

What that looks like in actual practice I don’t know but burying our heads in the sand and saying “it’s to difficult to stop” is not a good position to have.
