"Sailor Pluto" banned name? cannot create

[Packetdancer]

If it was already taken, the error message would have said "This name is not available" NOT "That character name cannot be used."

Not necessarily. In the words of the MNK optimization document from a while back, "Game's Haunted."

Yes, normally it'd return the "This name is not available." However, it's worth noting that I've seen character creation do Wonky Strangeness when the person with a given name is currently off the world where you're trying to create. (I.e., they're doing world-visiting, or they're online but in Eureka or Bozja or whatever.) In which case, the short, computationally-cheap name check done during character creation seemingly returns a "Hey, that's not a character on this world!" but the presumably-more-computationally-expensive-and-thorough check done when it actually attempts to create the character still fails out -- quite rightly -- because the name is in fact in use on the server.

I saw Sailor Pluto in Behemoth when searching in Lodestone. Only lv2 in 1 class, though.

Should've been Sailor Venus instead obviously.

I mean... that's what happens when you use names from anime and shows? You'll start seeing people adding a ' somewhere in the name or adding an extra letter

Funny you say that. Just the basic name search shows Behe has both a Sailor Pluto and a Sailorr Pluto. And im sure i could find more if i changed my criteria a bit. You pick an unoriginal name, you deal with the consequences.

Ironically, I believe the poster is a troll. The username, MoltresRider, is a massive hint towards that.
I'm not going into detail because that's personal life of someone else, but that's like someone going to a forum and naming themselves "Chris-chan".

Not on the same level, but that's still an obscure username.

Maybe Sailor Uranus is available.
