I think for me it has to be the ones who read everything but never comment. I saw some girl on a YouTube video awhile ago who commented on it saying she NEVER comments on videos but had to that time lol. I went out with a girl once who told me the exact same thing too. She watched lots of videos and read lots of comments yet she proactively chose NOT to ever do it herself. Like wtf? lol. It's as if these people are scared of being found or whatever.
