Heyo,

those organizations are surely doing crawling directly on the Tor Hidden
Service, but it's also possible that they are doing it from Tor2web.

Also the German agency wrote sometime to abuse@, while the italian rely
on national DNS-based censorship for CP sites (but have no evidence that
they are doing it on tor2web.org).

Btw i think that we shall start by asking ourself:

"How can we detect that someone is doing a crawling without much false
positive?"

If we can do that, we would be able not only to remove them out from the
statistics, but also to "Automatically act" on the crawlers.

What do you think?
