Facebook told Reuters on Tuesday that it would extend some of its 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. As the largest social media service in nearly every big country, Facebook since 2016 has become a means for politicians and their adversaries to distribute fake news and other propaganda. Buying Facebook ads can widen the audience for such material, but some of those influence efforts may violate election rules and the company\u2019s policies. Under pressure from authorities around the world, Facebook last year introduced several initiatives to increase oversight of political ads. Beginning on Wednesday in Nigeria, only advertisers located in the country will be able to run electoral ads, mirroring a policy unveiled during an Irish referendum last May, Katie Harbath, Facebook\u2019s director of global politics and outreach, said in an interview. The same policy will take effect in Ukraine in February. Nigeria holds a presidential election on February 16, while Ukraine will follow on March 31. In India, which votes for Parliament this spring, Facebook will place electoral ads in a searchable online library starting from next month, said Rob Leathern, a director of product management at the company. \u201cWe\u2019re learning from every country,\u201d Leathern said. \u201cWe know we\u2019re not going to be perfect, but our goal is continuing, ongoing improvement.\u201d Facebook believes that holding the ads in a library for seven years is a key part of fighting interference, he added. The library will resemble archives brought to the US, Brazil and Britain last year. The new-found transparency drew some applause from elected officials and campaign accountability groups, but they also criticised Facebook for allowing advertisers in the United States to obfuscate their identities. The Indian archive will contain contact information for some ad buyers or their official regulatory certificates. For individuals buying political ads, Facebook said it would ensure their listed name matches government-issued documents. The European Union would get a version of that authorisation and transparency system ahead of the bloc\u2019s parliamentary elections in May, Leathern said. The ad hoc approach, with varying policies and transparency depending on the region, reflects local laws and conversations with governments and civil society groups, Harbath said. That means extra steps to verify identities and locations of political ad buyers in the US and India will not be introduced in every big election this year, Leathern said. In addition, ad libraries in some countries will not include what the company calls \u201cissue\u201d ads, Leathern said. Facebook\u2019s US archive includes ads about much-debated issues such as climate change and immigration policy even though they may not directly relate to a ballot measure. Australia, Indonesia, Israel and the Philippines are among nations holding key votes this year for which Facebook said it is still weighing policies. Leathern and Harbath said they hoped to have a set of tools that applies to advertisers globally by the end of June. They declined to elaborate, saying lessons from the next couple of months would help shape the worldwide product. Also read: Will Etihad raise stake in Jet Airways? What Naresh Goyal-led airline has to say about resolution plan \u201cOur goal was to get to a global solution,\u201d Harbath said. \u201cAnd so, until we can get to that in June, we had to look at the different elections and what we think we can do.\u201d Other Facebook teams remain focused on identifying problematic political behavior unrelated to ads. Last month, researchers working for a US Senate committee concluded that the Russian government\u2019s Internet Research Agency used social media ads and regular posts on inauthentic accounts to promote then presidential candidate Donald Trump to millions of Americans. Russia has denied the accusation.
