People actually get rich if the idea posted is crazy enough to grab attention. Here's some examples
- Grilled Cheezus is an electric sandwich or panini press that toasts the face of Jesus onto your bread. The project exceeded its $25,000 goal by a modest $604, which wasn't enough to reach any stretch goals (stretch goals are additional features project creators will often add to encourage more funding), but if backers who forked over $35 and up for the toaster choose the right cheese, their sandwiches will be plenty stretchy already.
- Potato Salad: Zack Danger Brown asked Kickstarter for $10 so he could make potato salad. He hadn't even decided on what kind yet. Before the campaign was over, Brown had raised $55,000.
Just little things like meat soap are found humorous enough that someone funds it to be made. There's also gofundme, this one's tailored more towards your interest i'd imagine as it's just about giving someone money.
Recently this black guy put up one for racists to send him back to africa and it's actually produced him 1.8k
