This is from the naming guidelines on the Pirates Online site.

"Avatar Naming Guidelines:
  • No foul language
  • No inappropriate mixed case. For example: Neither JoePirate nor joEpiRAte. Joe McPirate is ok.
  • No Disney characters or other cartoon characters
  • No exact characters from the Pirates movies and no mixing of exact character names. For example: Elizabeth Turner, William Sparrow
  • No sentences
  • Names must be at least three letters
  • No names that imply that you're a Disney employee
  • No names with titles already in them. For example: Captain Anne, Mr. Smith
  • No copyrighted names
  • No non-English words
  • No religious names
  • No references to anything illegal
  • Apostrophes, Periods and Dashes are the only punctuation/symbols allowed, but must be separated by a letter.
  • No personally identifiable information. For example, you can't use your own name"

Nothing illegal??? We're PIRATES for crying out loud! We steal stuff for a living. LOL
