Unfortunately, that happens quite a lot in the adult industry. For example, Kayla Kayden uses an alias Lacy Spice. Lacy Spice is also the name of a Playboy model. I've also seen camgirls at MFC, ImLive and Streamate use known pornstar names. Crazy, right? But it happens. The difference between the camgirl and the pornstar? A few numbers or letters after her camgirl's alias. One webcam model spelled her name with three additional "i's" in her name at the end and then further used "666" after that. Yes, she was into the Satanism, the occult and mysticism. Sometimes the known pornstar will put, "_xxxx" after her name to make the distinction between herself and that camgirl.
Stick with Pumpysworld's name for this girl. And mark this thread solved.
