About the prank with ink, i would call it cruel from parents, not sure i would use the word abuse, but hell, why do that prank to your kids? This rmeinds me about the fake video where parents have a kid believing he gets a Xbox by gifting him a cardboard box with the name xbox, then when he opens it there are clothes. The kid finally gets a console, but it is obvious parents amde fun at the expense of their kid, and i find that a bit cruel.
The prank itself,+ the public humiliation.
If you haven't been following the story, the mainstream news reports all hid the other videos where there is horrific physical, mental, verbal, and emotional abuse all in high abundance. These kids were getting the shit beat out of them in a daily basis by the parents and each other. The little boy alone has several bleeding wounds and scars in nearly all the videos.
Take that in. The little boy is bleeding in a lot of their videos from the "pranks" pulled on him
