Here is another page someone dedicated to the little boy (also 2013) to show that is really his name: https://aspacewith.wordpress.com/2013/04/10/felix-mclean-artist-chat/

On the boy's google+ page, in addition to a photo of a pez dispenser, there is

1. Deleted video titled "Help Me"
2. Comment "if you liked it pleas like coment or subscribers to have Henry go to raping School"
3. Deleted video titled "Raping Henry"

Look I am a CSA survivor, I have PTSD, I started shaking and having a panic attack when I stumbled upon this, it is possible that I am not looking at this objectively/clearly, someone who is calm/objective please analyze whether or not this is cause for concern.
