Mapping College Rapists with SHA2 & Tor

It would be trivial to brute force the alleged perpetrator's names, simply by running SHA2 on all students. This is not helped by adding a unique salt, because then no matching can be done between incidents.

I applaud the ideas and ideals, and I believe this has the potential to be a Good Thing(tm). I'd really like to see clever and knowledgeable people get together to make this happen, and the ideas outlined here are at least a start.
