Enter the RMT PWNER program, version 1.337. (No, we totally did not make that up.) This program can parse the many servers of FFXI for information regarding the buying and selling transactions of a character under suspicion of the task force. The program will then list all characters who have associated with that character's associates, and so on and so on. This way, the task force will be able to easily track all members of a supposed RMT group without doing all of the human legwork of tracking through endless log files.
