Nah, I don't judge them and say they don't have a life. I'm actually jealous that they don't have a life. I'd love to live off my parents and not have to go to school/work. They don't know how good they have it.
I just think it's a bit weird when someone gets a high post count in a very short amount of time, keeps me wondering, but that's far from judging.
Everyone can do what they want to do.
