Look at her nicknames... it is obvious she will NOT show her face. I don't know if she freaks out if you ask that. But why would you waste your time asking a girl named "b0dybutnoface" and "FacelessAlex" to show her face? And it seems clear why she does this. Wanna make money as camgirl but without the risks that this job brings.
It is indeed a big turn off. She got a nice shave pussy, speaks english well. But spending the whole time in private just watching her rubbing her clit quietly without seeing her face, at some point, is just boring. She barely moves. It is always in the same position.
