Yes there is. They port scan to find IP addresses with port 6346 open. Any computer that returns a SYN/ACK or ACK packet (or an RST, PSH, or FIN packet depending on the type of scanning they are using) gets thier IP address added to a list. From there it can be used for just about anything. The agencies can use it see how many files you are sharing, and what they are. Or they can use the open port to deliver advertisments, spyware, or even gain unauthorized access to your computer. The job of a firewall and PG are to close/monitor open ports, and block all incoming TCP packets from prying agencies. I hope this helps.
