Donie O’Sullivan for CNN:

Late Wednesday, Twitter made waves by temporarily restricting a Trump campaign account’s ability to tweet because it shared a video containing false claims President Trump had made about the coronavirus. But Twitter took no action on President Trump’s personal account, which re-shared the video.

The next day, Facebook cracked down on a pro-Trump PAC’s ability to advertise after spreading falsehoods even though the platform has repeatedly said it will continue to allow politicians to lie openly in advertising.If all that makes your head spin, you’re not alone.

These examples are indicative of a much wider problem for the big tech platforms: At a time when Facebook (FB) and Twitter (TWTR) have put a greater spotlight on themselves by taking action against posts from Trump and accounts linked to him, the companies’ rules for handling content generally and political misinformation specifically remain so confusing, so ad-hoc, that even the staff at these companies sometimes struggle to comprehend them.
