My face is one of my best features but I wouldn't show my face even if it meant more business or a higher rate. Both of which I could easily do if I posted face pictures.
You never know what the future holds. What if you want a certain type of job someday and someone there happens to recognize you from pictures. Strange things happen. I would want to try and protect myself from any and all negative consequences associated with the hobby. The real world will not understand or accept your reasons. Not ever.
We all make mistakes and slip up. We are human. But the less of your identifying features that can connect you to this the better. That includes tattoos, moles and birthmarks. If you have anything in your pics someone could identify you from, I'd fix it.
Just my opinion. Not everyone thinks or feels the same way. But you asked. Have a great weekend. Good luck.
