I don't think scams as so much as inexperienced people who say "I've been doing this for X years and I can totally do it" then after spending 90% of the money and 6-12 months late - they go "actually....I don't think I can do this". This is also due to the fact that most projects try to do things at cost rather than allocating some buffer. There was one posted for a bluetooth controller - looked pretty nice and I believe they even had a prototype. When the due date came - excuses start flowing in such as some company in China wanted to charge more than the initial quote for the cases. The owner even claimed it would be too expensive to 3D print them (which I think is a lie - the printer itself is expensive but the amount of filament needed per case wouldn't have been that much). Granted, using a 3D printer probably would have taken another year.
