Three weeks ago, Facebook and its founders faced a lot of criticism after US President Donald Trump wrote controversial posts that left the platform.

Then they promised to review the rules. And although that work is not yet clear, Zuckerberg presented some of the new measures that will be introduced.

"Many of the changes we are presenting today are based on feedback from human rights movements," writes Mark Zuckerberg, who also broadcast live on Friday.

Do as Twitter

Without mentioning any names, Zuckerberg writes that politicians' posts that violate Facebook's guidelines may be flagged as an alternative to erasing them. This is because the posts can have a news value.

Twitter took similar action when Donald Trump tweeted during Black Lives Matter protests that broke out across the United States just over a month ago.

The act, in turn, led to Trump writing a presidential order that, according to the president, should mean that social media companies no longer have any protection against legal sanctions for what is published on their platforms.

Facilitates voters

In addition to flagging, Facebook is also launching a campaign to help people get accurate, and official, information for the 2020 presidential election, it says. It is about both early voting, but also information on how to register to vote. Something all voters must actively do in the United States.

A power grab will also be taken against false data that intends to prevent voters from voting, Zuckerberg writes.
