The server overloaded and new players can’t download the game so I was wondering is it legal or not to purchase account with full game already purchased for ffxiv?

against ffxiv ToS? yes
but whatever, a lot of things are

I mean is it legal or against tos in jsp? Like can I get ban for posting it? There’s plenty of illegal things in square Enix or other games but everyone do it

Unfortunately, I believe it is illegal.

However, I think there is a grey line. Because when it came to Diablo 2: Resurrected, a member could post an ISO (In Search Of) for another to buy them the game for FG, but a member could not post a FT (For Trade), that they are selling an account.

Oh ok I see thanks
