I'm still amazed that people are still talking about mod/addon/cheat on the forum, seems like some people really need a reminder of the user agreement.

2.1 Cheating and Botting.

You may not create or use any unauthorized cheats, bots, automation software, hacks, mods or any other unauthorized software or hardware designed to modify the Game and gameplay. In addition, you may not take advantage of game system bugs and exploits during gameplay.

[...]

2.6 Hacking and Circumvention.

You may not hack, disassemble, decompile, or otherwise modify the Game or server computer code, whether the Game code is located on a DVD, Blu-rayTM disc, your computer/console or on Square Enix's servers, except as expressly permitted by Square Enix or applicable law.

2.7 Modifying or Creating Derivative Software.

You may not modify or cause to be modified any files that are a part of the Game or Service in any way not expressly authorized by Square Enix, and may not make any derivative works of the Game.

---------------------------------

When you play the game you accept those rules, meaning that if you ever do one of those action, you may be banned temporaly or permanently.

No matter if what you do harm other or not. The rules are here and Square Enix is the only entity that decide if you take the ban hammer.
