I don't think you need to be involved or have an enemy to get your account stolen
Maybe it just happen you are the victim on randomly target.
If it really a keylogger problem, then i don't know..
If you have feel unsecure about logggin into pol/ffxi, make the setting on pol that automiclly logged into the PoL, without need it to type in your password and id. is very opposit of that you think, if key logger is really targeting you, you don't really need to worry because you switch the setting to automailly sign on before keylogger targeted you, and I don't think there is anyway they can read the dot lol unless the hacker really a veteran one and decode crap lol
There is a way to protect your account
1) Keep Firewall on at all time even during online game play
2) Keep your password and id safe and out of reach from anyone
3) Don't let your friend even your own family know your password and id
4) Don't make a simple password name like "Iownyou" or "Sweets" Those are easy to be hacked, use number and letter like "Ae451Ffq6"
5) If you taking a long break from FFXI, call the PoL hotline and say you want to supend the account, so there is no way hacker can hack your account that have been suspend, and won't leave open during your breaks.
6) Don't have the same password or id name from your e-mail address or any other website that you registered on
7) Scan your computer for virus, spyware, or keylogger software in your system, I think antivirus can detect keylogger in your computer now
8 ) Don't download any 3rd pt software that enchance the game, if you do use something, use it at your own risk.
9) If you buying gil from Ige or any website that sell game money, never give them your account info except for a character name. Use different credit card to purchase gil that is different from the credit card you use to pay your monthly fee
10) When you call your friend that you really trusted, don't tell him your id and password on phone, some phone have static and sometime someone can hear your convosion even those you did do 3 say, etc, This Happen to my friend when he call me, we was chatting, then for some reason there is a statics and we heard some mexican people speaking on a background, then we can hear it clearly what they say, even tho we don't understand, then my friend acting all funny and see if they can hear us, so he started to make a joke and some racist joke to see if they can hear, funny thing they hear it, then he start cussing and make some funny stupid joke to piss them off lol then they hang up. Soooo basicly tell your friend personally about your id and password if you really trusted that person/friend.
11) Don't use Friend List Plus from the PoL offical website, because it required your id and password, your computer could be hacked just at a right time and in a right place.
11A) Don't check your friend list in school computer using Friend List Plus
12) Alway keep your billing info and your registion code in a safe area incase you really need it in an emergancy so you can have proof.
