Same operator - 1 listing

Published under a different store account, but sharing the registered address, contact or declared legal entity this one gave the store.

Shared hosts - 1 hostname

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.
