The Internet is overrun with child abuse images.

Great, yet depressing, summary of the current situation from the New York Times, More can always be done to combat the problem.

Most of my time is spent helping companies investigate thefts of property or money. It's one thing to catch a criminal who stole some property or some money, it's a completely different feeling and reward to rescue children from horrific abuse.

This difference is why I built a dark web crawler in 2013 to help preserve evidence and catalog sites for an agency, joined HTCIA, work with Interpol, and generally assist with criminal investigations.
