While I do stand corrected in a chapter or two, my favorite example was a popular "female" streamer who was a guy and made a tutorial on how to do what he did. Just wear the top of a dress, shave where you don't want hair seen, and viola, a pretty face and curvy figure are seen on stream. It's actually rampant, especially in China. Which I find hilarious, fascinating and terrifying.
There was a 50 something female CEO who's profile picture looked like a super model. Honestly, it was hilarious because she was discussing serious things and her profile pic is on the projection right behind her.
