I have known several, most of them legit. However, there was one where a bride-to-be that I knew set up a page last year to fund her honeymoon to some European country. She received a lot of backlash and the story ended up on the local news. She has been married now since February and they still haven't taken their honeymoon. I think they are going this month. He page raised $1100.
Another page was set up for my nephew's wife who claims she has a form of acute deadly leukemia that she doesn't have. She is a habitual liar. She dug herself into this hole of a lie and her younger sister set up the Go Fund Me page believing her sister only had 2 months to live and wanted her sister and sister's husband too have a nice vacation before the sister passed away. I think she raised around $500 total. It's been 2 years since my DN claimed she had this cancer. She has never had chemo (said she can't because she has blood clots), but has taken many trips to the Mayo clinic in Phoenix for "treatment" where her and my nephew and kids stay in her parents' time-share condo for weeks at a time. Yet no one has ever gone to the hospital with her for said treatment. She claims she is getting radiation, but then comes back to the condo and posts a photo of her nursing her DD and food photos of a huge meal they were eating. If she had this cancer she would have been dead long ago without chemo and if she were getting radiation, she would not be near her kids that day, let alone nursing. Her parents gave them a new vehicle and are funding these "treatment" trips. They also own the home that my nephew and her live in. Neither of them work.
My brother does have an incurable form of cancer (but it's not acute) and his doctor is the same doctor that DN says she has, probably because she couldn't think of another name when asked who her doctor was. My brother was talking to this doctor one day during a check-up and mentioned the niece and her treatment and the doctor shook her head and said he must be mistaken and that she as not treating DN fo cancer. When confronted, DN sticks with her story.
I will set up a Go Fund Me page for my bother if he needs it in the future. His cancer is back now after being in remission for 2 years.
