Why would you want to hide the list of current and completed games?
You can learn from your own past games. You can review them. You can figure out what mistakes you made so that you can play better in the future.
It is a good thing to have your games shown. As a free member, you can only see your games from the last 30 days, so you should take advantage of having them available to you. (They stay visible to premium members.)
It looks like you have started to play a lot of unrated games. Why? It keeps your rating from declining further but it is better to have an accurate rating so that you play players you have a chance of beating.
