Facebook and adoption

Well I am a facebook stalker and I created a facbook just for bio family and blocked them from my "real" facebook, that way I can watch what goes on there and if I feel its a threat to my kids I will request them be removed but I have always looked at bio family like this "If it werent for them I wouldnt have my sons" so I feel that the deserve and have a right to have the pictures on facebook if they are old and from the time that they had custody of the boys. As far as new pictures I have given them a couple via email and I always edit the picture with their new names on the picture and it usually is a picture of the whole family!
