The game also bans variants like "Bez0s" and "JeffB."
After confirming that variants of Bezos like "JeffB," "Bez0s," and "Be Zos" were also locked out, I tried just going by "Amazon." That word's not allowed either. These names are clearly not locked because other players have already claimed them. When a name is already taken, it says, "This name is in use." Names which include the words Amazon and Bezos, however, "cannot be used," which is also what New World says when you type in swear words.
