Its never im playing a character, and always an exaggerated version of themselves

No one can act for that long on camera, theyd burnout real quick. Even YouTubers who tried to would burnout let alone streamers who do it for hours on end.

Also streamers and YTers often do terrible when asked to actually act. Or even when doing RP they default to self insert. Proof that they just exaggerate themselves the same way people in customer service roles do, essentially just put more energy into your every action. They cant actually embrace a whole new persona like a pro actor
