"Vlogging" and Family Vloggers?

When I was in my first year of undergrad, my roommate had a calendar of "The Shaytards," who she said she had been watching for years.  Thinking it was a TV show, I was surprised to find that this was a family that posted YouTube videos and had millions of subscribers.  This was 2012, and their channel has since continued to grow.
As of this post, here is their video and subscriber count:

Here is a link to their Socialblade statistics, which estimates their earnings based on view count.

This is an image of their most recent videos.  It is clear from the majority of thumbnails, which feature several close-up shots of the family's children, that the young kids are being used to market their videos.  Some of the children have been videoed on the channel since birth.  With all of the discussion so far on this blog about the ethical implications of sharing children on the internet combined with the money, view count, and volume of videos, thinking about this family begs the question: What are the negative implications of the giant footprint being created for each child?

This article in the Sydney Herald discusses the ways that images posted by parents can be manipulated into child exploitation or abuse material.  With millions of frames of these children available for anyone to manipulate, these children are especially vulnerable to this risk.  This article argues that parents sharing extensive information about their children are imposing online identities onto them well before they can decide upon them for themselves.  There is also the clear issue of labour, as these children's talent is being used to make money.  Can anyone offer any thoughts about this family?

Below is one of the family's videos that summarizes their YouTube journey.  If you are interested in seeing more, Here is their YouTube channel and Here is a Forbes article on the family.
