Back when I was new to FR, there was a bit of a probationary period before you could post unmoderated. That seems to have gone by the way, but it wasn't really harsh to begin with. Maybe two, three days.
I've always been a talker, so I let loose as soon as they took the choke chain off. I stayed respectful and didn't get into spats with anyone, but I sure wasn't shy about sharing my opinions.
I don't think anyone's suggesting you quiet down. The poster may have actually been complimenting you on your output.
