Maybe something new will happen at the next election, but it will be harder to convince people with this type of fake news.
There's no differentiation between the 3 items in terms of visual layout, and the domains of the respective news items are visually deprioritized by Facebook's design. If you don't actually click through to "bigbluevision.org" -- and studies claim that 50-60%+ people just read a headline before sharing/moving on -- the claim that "Obama's Lawyers Official Admit Birth Certificate is Fake" has as much cognitive impression as ABC News's "Obama Calls Conversation With Trump'Excellent'". Seeing a bunch of fake headlines, over time, would seem to have the same effect as watching advertisements. The viewer doesn't have to do anything, but are affected nonetheless.
