Using profane names for characters, chocobos, fcs, retainers, why are people doing this? Isn't it obvious that this isn't appreciated?

Yes, its not nice, that GMs are not listening until the end. But like you said: you needed to wait really long in the prison. Would he have talked to you more, another guy in the prison had to wait way longer.

Something really caught my eye: you are only a sprout and have so many reports yet? You cannot say its your first offense, when you are piling up all these offenses. You have at least 3 inappropriate ingame names and verbal abuse by yelling at people. I understand why the GM couldn't decrease the punishment.

I am playing for 9 years and mentored so many people. And yes sometimes got into arguments. But I had never the chance to see the jail.
Try to stick to the rules of the community. People do not want to pay to play in a toxic environment. Even if you are paying your subscription, the people you yelled at payed theirs.
