Rapper B.O.B. has actually been a flat Earther for years and his last 2 (or 3 now?) albums have been based around the globe deception and other conspiracies. He didn't come out recently as your article suggests. Also he wasn't the one who took the spirit level on the plane and made a big deal about it. That was a YouTuber by the name of D. Marble, I believe. I can see how you made the mistake because they are both, um, flat Earthers.
This gofundme started out as $200k and must have just been changed in the last day or so. Anyway I tend to agree with you that this is a ridiculous thing for anyone to throw their money at. A million dollars could do some really indisputable tests right here on Earth with no space interests involved.
