On the anniversary of January 6, social media platforms are on high alert

January 6 was a clear turning point for major social media companies — proving that they would, under certain circumstances, be willing to deplatform a sitting US president. But some experts worry that they still haven't done enough to address the underlying issues that allowed Trump supporters and others on the far-right to be misled and radicalized, and to get organized using their platforms.

Ahead of the one-year anniversary Facebook-parent company Meta, Twitter and YouTube say they have been monitoring their platforms for harmful content related to the Capitol riot.

"We have strong policies that we continue to enforce, including a ban on hate organizations and removing content that praises or supports them," a Meta spokesperson told CNN, adding that the company has been in contact with law enforcement agencies including the FBI and Capitol Police around the anniversary. As part of its efforts, Facebook is proactively monitoring for content praising the Capitol riot, as well as content calling for people to carry or use weapons in Washington DC, according to the company.
