Now that you have your new toy (FFXIV), perhaps it would be time to get rid of the FFXI trial accounts so we can go without all these pesky gilsellers trying to get our attention. They werent used by the people they were intended for in the first place, but there was still a slight chance at it before. There's really no reason to keep the trials around now that FFXIV is out.
It's basicly a win/win situation for you now anyhow. If gilsellers want to send tells after you remove the trial accounts for FFXI, they'll have to buy and subscribe to the game again. Instantly get banned, and you made 12,95 plus whatever you made on the game and its codes itself.
Heck, they might even have to use their farming accounts now to send tells with, getting rid of even more of them. Lastly having to put so much work and money into it will most likely discourage them in the long run anyhow.
Lets work together to make FFXI more fun, fair and lacking gilsellers.
