> They’re a forum with user generated content and ads. They’re undertaking a huge moderation effort already — trying to have their army of underpaid moderators also police facts is just a problem that can’t solved because lies are cheap to spread and expensive to refute.
That argument is unconvincing, because Facebook already does fact check ads and disallows ads that lie. Here is their policy [1]:
> Facebook prohibits ads that include claims debunked by third-party fact checkers or, in certain circumstances, claims debunked by organizations with particular expertise. Advertisers that repeatedly post information deemed to be false may have restrictions placed on their ability to advertise on Facebook. Find out more about Fact Checking on Facebook here.
The controversy is over Facebook's recent decision to exempt political ads from this fact checking.
Political ads are only a small part of Facebook's revenue, so it is very hard to believe that they have the resources to face check all the other ads but not to check the political ads.
