Surprising, or maybe not, I was jailed by GMs unintentionally. I play on Xbox360, if it's somehow important in this story.
Last night, my LS was about to start handing out hourglasses in Buburimu when suddenly I instantly get booted off FFXI. During that whole in-POL, but can still try to log back in I got a message that literally said "Cannont log into Playonline for some reason". So I go all the way back to the first menu and try to log in, it prevents me from going into POL, but sends me straight to GM chat. At this point I'm thinking I probably got banned over something silly or the STF has taken interest in me getting a Shining Cloth recently when usually I'm extremely poor.
So I wait for my turn which painfully takes around 40 minutes. Finally I enter a chat with a GM, Promethus(or something similar), and he has me wait another 5 minutes while he "reviews the status my account". Finally he says "It seems your account has been confused with another one. You can now log in". I LOL'd and tried to take a picture with my cellphone, but it has shitty menus, so I don't think I saved it right.
When logging back in, I get another GM call within POL, so I answer it. This time it's from GM Claudius(spelling likely off). He basically says the same thing, only "There seems to be no reason for your account to be jailed."
After all that mess, I finally log back in Buburimu roughly an hour later.
Has this ever happened to anyone else? Good lord...

s. I told her I'd much rather see funding go to battle music for mages, recycled weapon skins, and a video of Red mages meleeing with staves that has some untold importance but looks really, really silly if you watch it for long enough.
