SAN FRANCISCO: Facebook on Monday said that it is testing a way to let members know when articles posted to the social network are tongue-in-cheek instead of hand-on-heart.

Evidently, users of the world's leading social network need a bit of help when it comes to discerning truth from fiction in the form of satire crafted to pushed boundaries of credulity.

Facebook told AFP it is testing a "Satire" tag to go in front of links to satirical articles that pop up in news feeds at the service.

"This is because we received feedback that people wanted a clearer way to distinguish satirical articles from others in these units," a Facebook spokesperson said.

Website literallyunbelievable.org lists a cornucopia of seemingly serious responses at Facebook to blatantly satirical stories, including pieces from The Onion, which specializes in the fake news genre. eat
