Personally, I feel much advantaged when no one can see my face.
And in truth, I usually don't want to see anyone else's face either. Aren't there companies that forbid looking at someone for more than five seconds? Well guess what, on a video call, they're staring at you for minutes on end.
Extremely unlikely Netflix actually has a policy like this. It was probably an example of what could be considered creepy in some circumstances during a training.
What should I look at conversing with another person? I used to look in the eyes or just in the face, I don't understand why is it harassment? Should I look at tits instead, is it less harassment or what? Shall I just close my eyes? West culture is weird.
