And of course
As others have already said, darth won't make it through the filter, neither will iconic Star Wars Universe names. I believe they also said variations will not make it through either, I'm sure a few will slip through the cracks but I'd imagine they would get reported or caught by the CR police on Day 1 or soon after and get a forced name change. Special characters are out for names as well but apostrophes and hyphens are in.
Darth Panda?????? naaah tooo easy...
Why use Darth in your name if you can have the Darth title anyway?
I have a whole 16Mb of RAM
The dark side is spreading!
I never got word filters on notable characters.
Who is to say Han Solo is not a common name in the Star Wars universe?
There's a relevant comic out there, not sure if it's Dark Legacy, where someone was trying to name his child after a hero of the horde, but couldn't. Was funny.
