Which is exactly like 50 Cent; people don't refer to him by his real name, they use the one they're familiar with: his stage name. The same applies to many other celebrities: 2Pac, Ludacris, Skrillex, so on.



I don't see why the same can't apply to Vinyl Scratch: people who don't know her personally may not actually know her real name so they just call her by her stage name. Even if they DID know, unless they're actually friends they wouldn't use her real name.



Vinyl, first and formost to most, is a celebrity. And as a celebrity she isn't exactly seen as a regular pony, so the same rules don't necessarily apply.
