I've recently applied for the character creation, and my name was "Sirca Prost". It was declined, stating misspelling and/or no capital letters. I don't see anything wrong with the name, unless I have to have such a common name like ex; John Smith.
There's no way to be sure exactly why it was declined without the person who clicked the button giving more detail. But I will say that it's fairly easy to click the wrong decline reason by accident (I've done it myself a few times) especially if your mouse is a little jittery.
I don't personally see anything wrong with it. Will it let you reapply with it?
We're only human, and mistakes do happen.

No Hal once a name is declined it cannot be used again using the automated registration method - only an ASim can then set a name to one that was previously declined.
