It actually seems a lot more wholesome that people are wanting a virtual "study pal" as motivation. That's pretty normal and healthy. We're a social species. If this helps people not feel alone and it helps them get started, there doesn't seem to be anything wrong with it. I'm sure some people also watch this guy because they think he's attractive, but at least he's giving them a positive stereotype, attractive because he's doing something good for his own development vs attention grabbing and attractive because skimpy outfit.
