Repeated sports games

I have been trying my luck with hollywoodbets, lose and win. The experience has been good so far. I do have a question though that has been on my mind lately. If a sports match has already played in the past, is it proper to schedule that same match,on the website for people to bet on it? I'm asking because I came upon a basketball match that had already played in the past, I know this because I had betted on it and I knew the outcome.
