"It is tough problem for platforms like Twitter and Facebook. They exist to allow people to share their thoughts and ideas … One of the things that I would like to see more of is, not to stop people from sharing things … but to warn them… So, when I am about to share something, and a reputable fact checking organization has shown it is a hoax, I would like Facebook to warn me “Hey … you might want to check, if this is true or not, before you share it”. I think that would be very helpful."
