If they're anon how do you know it's the same people coming back each episode? There are things that I don't care for and I've been vocal about it, but I don't spend every waking moment or even every week bashing it. I don't watch every episode of a show I don't like either, but that doesn't mean I might catch one every so often for whatever reason. I may give it another chance and find it still sucks (in my eyes) and then post somewhere about it and go back to paying attention to things I like. I could keep my opinions to myself, but then I'm able to express them so why not?
