I think banning ads is futile in the age of the internet and social media, also a retrograde step more suited to Catholic Ireland in the 1950’s or North Korea today. We have always had outside interference in our political affairs even before the internet. Newspapers, typically owned and run by foreign corporations, have been on sale here for decades and have never been shy in pushing their own political agendas in their publications. It may be more useful to require carriers of advertising to publish the source of the advertisements. It might have saved the US a lot of bother pointing the finger at Russia for interference in the Presidential campaign when all along it was a British company.
