Yeah, that may be true.. But Scihub is an onion site. That means there's not much in the way of "who", but in the way of last hop before hitting the onionsite.

And I would daresay that one should probably not trust logs when going through Tor.

I expect very few people visit scihub on Tor. The logs may be for scihub.cc, then?

The article doesn't have a link but likely refers to users accessing the clearnet mirror, sci-hub.cc
