Caution Concerning Use of Third Party Programs or Tools

As
indicated in the Prohibited Activities in Final Fantasy XIV, use of
third party programs or tools in FINAL FANTASY XIV is strictly
prohibited, as they damage game balance and allow users to gain an
unfair advantage over other players.

We have determined that a
number of players are utilizing third party programs or tools. If you
are found to have used such programs, your service account could face
disciplinary measures. Additionally, there have been cases of malicious
software being embedded in such programs, and users of such programs put
themselves at risk of losing control of their character in-game,
acquiring viruses, having personal information stolen, having their
account compromised, and being the recipient of any number of harmful
activities.

We would like all users to be able to play in a secure environment, and ask for your aid in adhering to our policies.

We thank you for your understanding and cooperation.
