When you publish your HSDir they'll come and crawl, and chances are none of them were expecting a 50PB archive.org mirror and just got stuck.
It's likely that once the operators of each crawler realized this HS was an archive.org mirror they stopped the crawls.
The early version of a crawler I ran across hidden services would have tripped up in exactly this way[0]
Everything else in this post is either a misunderstanding of Tor[1] or plain paranoia.
[1] the top exit nodes have little to do with who is crawling or attacking a hidden service, France and Germany feature heavily in nodes because of the many cheap Tor-friendly hosts, there is nothing 'unusual' about unnamed nodes and the AS confusion is just someone doing a good job of staying anonymous - thanks for reporting them
