Established rules on electoral campaigning, for example with regard to the regulation of political advertising, are often not adapted to the largely unregulated Internet, opening the door for non-transparent activities from domestic and foreign actors. Responsible digital political advertising, thus, requires action from political contestants (to uphold ethical standards), social media platforms (to improve transparency of political advertising on their platforms) and public authorities (to adopt laws and regulations for political advertising to the online environment). The latter includes a clear definition of political advertising and obliges social media platforms to make political advertising information public (see, for example, Report of the Kofi Annan Commission on Elections and Democracy in the Digital Age, 2020).
