I have 3 people blocked on mine and we aren't friends. I think you have to go into settings and select how to stop someone from bothering me and it should stop all contact.
Thanks queenie. I have someone I used to go out with when I was 15 wanting me to send him pictures of me. Scary. I think I might send him one of Les Dawson when he played that woman in the hair curlers (don't know if it was Cissy or Ada) That should scare him off!
