How is "impossible" a bad (aka, a "forbidden") word?

I want to use the word "impossible" as a part of my FC name, but I cannot.

Apparently Square-Enix thinks "impossible" is a naughty, bad, "forbidden" word.

Any ideas as to why?

Because it's impossible to name it that. It's like trying to divide by 0!

Thanks for your wondrous contribution to the thread. It isn't like that joke wasn't impossibly obvious.

Burn is also a forbidden word. Im not sure why either burn or impossible is out as far as FC naming goes.

'Siren' is another word that cannot be used for naming characters at least. Probably the same for FCs etc. (although I can almost see why, as it could be construed as being derogatory)

EDIT: A quick search and I find that I stand corrected xD In 2.0 you can use Siren, it seems it was only blocked in 1.0~

Could it be...

POS - Acronym for Piece of Sh!t?

Lol. Just say IMPOSSIBRU! Hahaha!

Maybe there's another FC with the name 'Impossible' and 'Burn' ?

Impossible is one of the words I used for the FC, but if I leave the FC just as "Impossible" it says it is the bad word.

I 2nd Impossibru, gotta get with the culture.
