My Mom is very into "Chat Forums." The problem is she gives out her address and phone number to people. The latest round involves a mental health forum where she has become involved with someone claiming to have multiple-personality disorder. She has taken to sending gifts to the different personalities. I don't dispute that there are people with this disorder, just that it's unsafe for my 83 year old Mom, or any one else, to be giving out personal contact info and sending gifts to the different personalities, talking on the phone with them etc. How can I convince her to stop for her own safety?
