I personally believe that inoffensive* content does not deserve policing. However, content that strays outside the bounds of common decency, probably needs to be censored. If a political campaign started advocating for the legalisation of child marriage, for example, despite it being a political ad, it is also far beyond the realms of common decency and should be censored. Similarly, for political ads that insight hate or xenophobia.
-- *Defining "inoffensive" is difficult, but that's part of your job if you're running the largest social media platform in the world. Once you filter out the bots, your own "like/hate" buttons should allow you to highlight the more controversial items.
