My nephew downloaded this because it is described as an "Adult blocker add-on". He took that to mean it would block adults like me from doing things like "hacking" into his computer, installing "malware" (parental control software), because he hates the "threats" to take away his internet privileges for a full year if I catch him looking up weird porn on Deviant Art, or watching YouTube videos that try to convince him he's really a girl.

How did I find out he installed it? Glad you asked.

My wife and I were attempting to use the laptop that evening for grown-up things and that's how I was introduced to Stop-it. I opened up the parental control software wherein I confirmed he installed it, and then proceeded to that part of the internet where, in this case, Bronies re-enact the Squat Cobbler scene from "Better Call Saul".
We had to have a long, awkard conversation with him about the whole thing.

****EDIT Because I know someone is going to call BS based on the fact that I have parental control software already installed....I don't want to give it a sales pitch but it's pretty awesome. it's basically spyware - he knows it's there and what the consequences are for breaking the rules. To this point, that had kept him from getting in trouble :) ***

Aside from the nature of the content the kid was looking at I thought it was pretty funny actually. Maybe better word choice in the description would be a good idea though.
