Instagram supressed a Dave Rubin book tour promo post: Dave Rubin, author and host of The Blaze podcast Rubin Report, made a promotional post for his upcoming book "Don't Burn this Country" that advertised his first tour stop and his guest, Donald Trump Jr. Rubin posted a screenshot on both Twitter and Facebook showing that the platform notified him that his post might be suppressed. "Messaging related insights such as shares and replies, may be lower than expected due to privacy rules in some regions," the platform warned according to a screenshot.  Rubin's tweet also said that "Instagram not only won’t let us [run book tour run ads] too, but they’re also limiting reach of my posts related to the tour."
