This was because it was known that the threat was delivered via tor, and
that he was the only one in $(organizational unit of harvard) using tor
at that time, and he confessed when being confronted with that. There
was nothing that actually proved that he did the threat. (Unless this
is a case of parallel construction, of course, which I don't assume.)

At the moment that would be prohibitively expensive. Also, it wouldn't
guard against the scenario above - you can't be online and shoveling
data all the time, so longterm correlation is still possible.
