One very important thing to keep in mind: If you generate a fake persona and present it as entirely real, you are being dishonest. This may not matter for inconsequential things like the pen name for your SubStack or something. However, it definitely matters if you plan to engage in anything serious or do any business under that persona. If you run into situations where you're forced to switch to your real identity (e.g. employment relationship, legal matters, or even an accidental leak) then you could lose a lot of credibility. People will naturally wonder if you were trying to hide something from them, regardless of your initial intentions.
