Facebook may have dropped the ball with the U.S. presidential election, but it was much better prepared for last weekend’s federal election in Germany. Today Facebook outlined all its efforts to prevent malicious actors from meddling in the election.

“These actions did not eliminate misinformation entirely in this election – but they did make it harder to spread, and less likely to appear in people’s News Feeds” wrote Richard Allan, Facebook’s VP of Public Policy for EMEA.
