IIRC, the mechanism has problems with collusion/dissembling. For example, one backer with $46 dollars and 4 backers with $1 each will get significantly better results by splitting their money into 5 contributions of $10 each. This seems like a problem that’s actually moderately likely to arise in practice.

Yeah, this and fraud are potential problems. They’re discussed in 5.2 Collusion and deterrence (pages 15 to 19).
