Honestly it seems like they more or less identified all of the former unidentified users, and it turns out the vast vast majority of which are on unix based systems.

If this goes right down again, I’d imagine the unidentified users to go up - But would be a decent indication for a lot of traffic being scrapers

Sounds like they figured out most of the previously unspecified traffic, comes from Linux based systems.

But you’re right about an unknown amount of that traffic is from servers.
