Probably the largest social media service in nearly every big country, Facebook has become a means for politicians and their adversaries to distribute fake news and other propaganda, since 2016.

The company has resolved to enforce political advertising rules and tools for curbing election interference to India, Nigeria, Ukraine and the European Union before significant votes in the next few months.

After being under pressure from authorities around the world, Facebook last year introduced several initiatives to increase oversight of political ads.

Nigerian advertisers who are located in the country will be able to run electoral ads, mirroring a policy unveiled during an Irish referendum last May, said Katie Harbath, Facebook’s director of global politics and outreach. Ukraine is expected to take the same policy in February.
