Community Names

[CremisiSteam]

I was wandering.

Graal###### accounts have a unique ID.
Other Graal Accounts had the chosen id.
As for the community name. Can it be the same as someone else community name? (If so than there would be no need for account names such as sephiroth123 because someone already got sephiroth as an account name.)

I actually wish there was a website out there that listed all anime / manga / popular game character names that companies could look up and REFUSE ANY AND ALL STUPID PEOPLE REQUESTING TO USE SOME FORM OF SOME POPULAR IMAGINARY CHARACTER for an account/user name.

You all have real names. Do you really need to copy some video game character/anime character/manga character?
