Why girls wear masks on their broadcasting?

Why girls use these masks now, i can't understand?!
I would understand if they wanna hide face to protect privacy, but Gosh, they have videos/pics with clearly visible face, but while do shows, they wear mask...
On Stripchat i find every day new girl with this, so i wonder myself what this mean

for me thats funny too, you can easily know who is under this mask,.. i do not showing my face , so only lips and and wear wig, thats for my protect because in the past i had stalker.. very terrible story so i deleted all account and chooising different name and different room to work, also i put pink wig on me, so lass change to be known .But i cant see different about earning, i mean i earning the same like with showing my face it looks that lips are enought for my client and in pvt when i already know the client i showing my face
