If someone connecting to your ORPort isn't a relay in the consensus it
is probably a client or a bridge.
In rare cases it might even be a relay. (IP address in descriptor
differs with current outbound IP address)

If you run arm [1] on your guard node you probably see clients as
"[scrubbed]" entries.
