I typed out a big comment criticizing the fact that the kid was also shown how to do the exploit, as opposed to figuring it out for himself.

But y'know what? Good for them. That's step one to figuring out their own exploits. And it makes you think: If even a preteen can pick up the gist of how to do the exploit, you could imagine paying someone to go around and try to run it on election day. They don't need to be very smart, just hard up for cash and willing to take a dumb risk.
