Pet peeve-People doing Go Fund Me's just to help them get something they want. For instance my sister just posted one to help her buy a house. No you can save or buy what you can afford like the rest of us. Not to mention that will make your life hell when it comes time to finance.
We had neighbors a few years ago that were like this. I was Facebook friends with the wife for about 1 week (which was 7 days too many). Every post was either a Go Fund Me request, her selling something, her asking for something for free or her re-posting a friend's Go Fund Me.
Every one of her requests was for something everyone else pays for (house, new car, vacation, etc). For an extra bonus, she'd sprinkle in a religious reference or a Bible quote for good measure.
