TechCrunch: Facebook fights fake news spread via modified link previews

TechCrunch: Facebook fights fake news spread via modified link previews. “Until now, any Facebook Page that posted a link could change the headline, body text and image that appeared in the News Feed preview. That allowed fake news distributors to bait-and-switch readers into visiting articles they didn’t expect, or make it look like legitimate news publishers were posting inflammatory or false headlines. But it also let real news outlets A/B test link previews, tailor content to different audiences and update previews as news stories evolved.”
