It has recently come out that Facebook is exempting political ads from its fact checking processes and rules, with a statement from CEO Mark Zuckerberg noting, "We don’t fact-check political ads. We don’t do this to help politicians, but because we think people should be able to see for themselves what politicians are saying. And if content is newsworthy, we also won’t take it down even if it would otherwise conflict with many of our standards."
His stance on stepping away from holding that power overlooks the fact that Facebook already has that kind of power for other ads, raising the question of why in regular ads, Facebook can be okay with using outside fact-checkers, and banning false claims outright, yet in political ads it can't do the same. It is an interesting topic to discuss with your children relating to misinformation online. Also keep in mind you can edit your Facebook Ad Preferences, and remove anything that you don't agree with or doesn't look right. You can also check out Facebook’s Ad Library, which now includes a new tracker of Facebook ad spending by major political candidates. It is a bit of an eye opener. Interesting enough, on the flip side, Twitter has banned all political ads.
