I read a lot of comments that sounds to me like: "I don't understand how this could work so it must be fake!" To me that is self-overestimating.

Personally I fully don't understand how it works, but I think it's fantastic.
With me someone is innocent until proven guilty. Let's wait for that and hope for innocence. I've seen to often that people make facts of their own speculation.

If you want to swindle a group of people, wouldn't it be wise to pick a group of people that isn't above average intelligent?
