Facebook's new security process

Facebook has changed the many things about the privacy of the members. Now one can control the amount of information he/she wants to share. This was created because before a person which has mutual friends can see your information by seeing your friends posts like photos. I know that there are many pervs in the internet that only add you so they can stare at your photos. Before, even if you did not add them they could see your pictures. Now thanks to this new system this can not happen. I agree with this new precess.
