If it's a word-name or an alternative spelling of a name, it might be annoying (especially in the case of the latter because everyone will assume incorrectly), but at least there's some kind of reference for explaining the name. If it's just a random jumble of letters, you don't have this sort of reference and chances are that you have to literally spell it out every singe time. Though personally, it really makes me cringe when parents blatantly name their children after something from whatever fandom they're into. Something like Luke as a Star Wars fan is perfectly fine, but if it's something like Khaleesi or Naruto or fucking Sodapop - go away.
