“We want voters to be aware of who is trying to influence them. That’s the reason we have disclosure requirements on our campaign ads. We’ve known, at least since Aristotle in Western culture, that the source is judged as part of the message.”

— Kathleen Jameison Hall, author of Cyberwar: How Russian Hackers and Trolls Helped Elect a President — What We Don’t, Can’t, and Do Know (Oxford University Press, 2018), as quoted in How Russia Helped Swing the Election for Trump, by Jane Mayer, New Yorker, 24 September 2018
