A notorious flat-earther, David Weiss, has for quite some time now issued a Kent Hovind style "challenge" for anybody to give him a single proof of a globe Earth, the prize being three bitcoin. What is a "Kent Hovind style challenge", you might ask? It's a type of impossible-to-win challenge that was popularized by the infamous young-Earth creationist Kent Hovind: He offered thousands of dollars for anybody who would give him a proof of the theory of evolution. The problem? Not only has he not given any description of what he would consider valid proof, but more egregiously, Kent Hovind himself is the only and sole judge of whether your proof is valid or not. Thus, it's a very easy and safe "challenge" to give: He can simply reject all proofs given to him (usually just by saying "that's not evolution") and he doesn't have to pay. Because he is the only and sole judge, he is the only person who decides whether he has to pay or not....
