Hulu’s new three-part documentary series gives a behind-the-scenes look at the events leading up to "momfluencer" Ruby Franke’s arrest on child abuse charges.

Ruby Franke, a former YouTube family vlogger, gained fame through her now-deleted 8 Passengers channel, which documented her family life. Initially popular, the channel became controversial due to Rubys extreme parenting methods.

The estranged husband of Ruby Franke -- a mom who rose to fame on YouTube and later pleaded guilty to child abuse -- is now speaking out to warn other families about the dangers of social media.
