Unfortunately, the hardcore sites are/were advertised on one of the 20+
hidden wikis which exist at any time. The press and police only seem to
find these sites and assume everything is just this set. There are
seriously 20+ hidden wikis, each one claiming to be the
original/canonical wiki.

Given the resources of a national police force, it seems probable they
can create a crawler to simply crawl every permutation of hidden service
addresses on port 80 alone.

Of course, it's easier to crawl the 20+ hidden wikis and go from there.
