For entire classes of online crime, from a purely data perspective I wonder if providing a way to anonymously report a crime would help? Things like extortion, cheating spouses, lewd photos, revenge porn tend to be quite embarrassing, and perhaps pursuing justice isn't worth getting exposed. But knowing names, emails, patterns, and other details might help at least paint a better picture of the true nature of online crime.
Sounds like a channel that would be instantly DDOSed for a number of reasons. Criminals would want it down, and the usual people with issues around law enforcement would want to hurt it, while younger people would potentially do it for shits and giggles.
