The Wall St Journal has run stories about fake news on page 4 and page 1 of the business section for two days in a row. They deplore it.
My Facebook has been running fake celebrity obits for a week now. I have been informed of the death of Clint Eastwood, Angelina Joli and three or four others. All fake. Which has pretty much destroyed my confidence in anything else I might see on Facebook. I use Facebook to post snapshots for my widely scattered children and friends. Nothing more serious than a seven year old's birthday party, or autumn leaves in NH. But after all the fake obits, I don't trust anything more serious from Facebook. Dunno about twitter, I don't do twitter, although maybe I ought to start to catch some of the Donald's rants. Haven't seen anything fake on Google, yet.
Was I running any of these web sites, I'd clamp down on fake news, just to retain the ordinary user's confidence in the site.
