Here are a few thoughts on botting and how to stop players from doing this action.
1: Make it so any changes done to the system required to log into FFXI makes the game unable to launch.
2: When someone is reported to be maybe using a botting system. Give the GM's enough power or the ability to watch said player or 'tag' them for an action and have said action monitored over the course of a week or more. If there is a pattern to the players actives that places them in botting or RMT category they get jailed or banned.
3: Look for a way to disable all third party software and coding from being allowed to operate in the system files it is installed in. (There are several ways of doing this, one is posted above.)
4: Listen to your players and people paying your checks... If your player base isn't happy about certain activities, change them!


Making gil in FFXI can be easy for some but if you don't have a ton of time or you hate crafting, making gil can be the bane of your existence. Players like myself would rather spend a few hours farming NPC'able items and selling them to make enough money to scrape by but others may love crafting. Each player has their own way of doing things but the point in this game that most everyone agrees on is making money is always irritating or time consuming. RMT's wouldn't have business if players didn't struggle so hard to make money themselves.
