On the Name Entry screen, when attempting to submit an inappropriate name (i.e. profanity, sexual content), it will instead be replaced with a different, more appropriate name. Humorously, this also applies when attempting to submit the names DDR (an abbreviation for rival series Dance Dance Revolution) or 573 (The "Konami Number", Konami being the company behind DDR), as they will be replaced with "SMX" (abbreviation for StepManiaX) and 123 respectively.
