Amazon blocked The Heritage Foundation from running ads for an investigative book on BLM: Mike Gonzalez, a senior fellow at the Heritage Foundation and formerly a Wall Street Journal journalist, recently released a book entitled "BLM: The Making of a New Marxist Revolution." Amazon blocked The Heritage Foundation's attempt to buy an ad for the book, allegedly claiming that the ad "no longer compile[d] with [its] current creative Acceptance Policies," according to The Daily Signal, The Heritage Foundation's news site. The ad also explained why the ad was banned. "Your ad contains book/s or content that is not allowed. Content that revolves around controversial or highly debated social topics is not permitted,” the notice read. “Please remove this content from your ad.” The Daily Signal later reported that Amazon reversed its action and claimed that "[its] policies were inaccurately enforced" and that it was "providing training to ensure [its] teams are clear on [its] policies.”
