Mrfunkedude, 
FOR FUCKS SAKE PEOPLE!!!
If you EVER see a grown man scrolling through Instagram looking at pictures of kids and zooming in on certain parts of the kids, SAY SOMETHING.
As loud as your fucking voice will carry ask that person "WHY ARE YOU SCROLLING THROUGH PICTURES OF CHILDREN ON INSTAGRAM!?!?"
Embarrass the FUCK out of that man. Make him run out in shame with everyone looking at him.
Otherwise to do nothing you are COMPLICIT! SO FUCKING DO SOMETHING!!!
