i have 3 accounts linked to my square enix id (1 mine 1 of my brother and 1 extra that i had lying around) and this 15th of december my brother was playing like normal after i rage quit because of the cap fight and he suddenly got booted out of the game and when he tried to log in the account was temporary suspended also i loged in on the other 2 accounts and it said the same thing

we didnt do anything wrong as far as i know he was in abyssea la thiene in a frog party and i was on bastok
and the other account is canceled because i dont have anough crysta to pay it

it was because the hacking attempt to the SE Servers or what?
also has anybody had this issue or its just us?
