Would be interesting to see if you could infiltrate this network if you had obscene amounts of money for some reason that you didn't really earn, like if you latched onto Bitcoin early or something, buy it and see if you can get further in the chain, though if you succeeded and reported it, corrupt LE might just come after you instead.

Would also be interesting to make a bunch of these listings, fake, but with known pedo symbols and such, and see if you can get some random to buy it. Listing on most sites is close to free, also insanely risky and stupid of course.
