Other then blocking them, the only next choice would be to change your profile. I would send a private message to all those you wish to stay in contact with and let them know you are changing profiles. Lots of people change profile, no reason to let them know why. Sucks family has to be that way - but the best response you can go is "Hit the ignore button" dont give the satifaction of responding it just eggs them on. Some people just get a thrill out of making others feel bad. Gee's wish I could go around and slap them all across the face.
