Who publishes it

Paperpile LLC - no other listings under this identity, 15 shared hostnames

What this publisher told the store about itself, and the other listings that told it the same thing.

Paperpile LLC

Shared hosts - 15 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
