We're talking a lot about changing names, but in my personal opinion (and having watched different models succeed/struggle over the years..) I would highly recommend putting a lot of thought into your name so that you don't later change it completely. Changing part of it...totally fine, and understandable if you have a limited time fetish going on. But other than that...
There are SO many girls on the internet doing this. I'm pretty active in the camming community and I know sometimes my head spins from all the different names and girls. It's easy to get lost in the shuffle. Your reputation and brand is very important. I have seen name overhauls backfire time and time again.
You want your name to be more than just a name. For example, when I say Sophia Locke, it's not just about a very sweet girl with a high pain tolerance. It's about jenga, the cam mansion, an incredibly unique style of camming. When you think of Amber Cutie, it's not just Amber, but the empire she's created. IMO that is the key to a successful name/brand. When people see "Veronica Chaos", I don't want them to just think of me, I want them to think about the world I created, I want them to wonder about the future of this world. My case is slightly different because I plan on using my name as my performer/stage name for my entire life in different creative endeavors, but the concept is still the same. My name works on several levels: It's a "real" sounding name (people know me as Veronica), it allowed people to give me a cute nickname that is also recognizable (VC) and it also describes my show/world (which is really chaotic). It allows me to experiment with my style, since "Chaos" is pretty vague, but distinct enough that it has worked with the different weird camming styles I've tried out. I think, if you want longevity in this job, it's important to give yourself a name that is flexible enough for those changes because so much of camming is adaptation.
I would highly encourage girls to choose at least a "real" sounding first name. It humanizes you and allows your fans to connect more easily. Part of our jobs is to make that connection for them as easy as possible.
