Question about using a Copyrighted name

[Ajido]

If they do enforce it strictly then like 30-40% of players would either get banned or forced to rename.. :\

Personally, I can name several players on Cactuar that would lose their names if they get forced to change it.. Including someone named Final Fantasy.. xD

Banning seems kind of harsh, I would assume they'd just force a name change. It'd be nice to get a response from Square on the issue and how they plan to handle it and what players can do/expect.
