Facebook has seen an increase in signals indicating potential future acts of violence associated with efforts to contest the results of the U.

S presidential election since the capital siege last week, a company spokeswoman told Reuters.

Alarming new signals Facebook tracked included digital flyers promoting the events, some of them featuring calls toe arms or the insignia of militias or hate groups.

Twitter and Facebook blocked Trump's accounts, while Amazon Web services and the major mobile APP stores cut off Social Media Network Parlor, which had been used as a tool by Trump loyalist to communicate ahead of last Wednesday's events.

Speaking at the Reuters next conference on Wednesday, Alphabet CEO Sundar Pichai said YouTube is monitoring trumps YouTube channel in line with its three strike policy.

So we've been removing, you know, you know, thousands of videos, uh, including videos from President Trump's channel.
