there is a rich history of this kind of bounty marketplace in "dark web" writings. the idea is the higher the bounty, the more incentivized the politician is to act right. and if crowdfunding is opened up to their whole political constituency, there are a lot of people available to vote with their dollars. I don't know that I endorse this because I am opposed to violence and coercion, but I can see the logic of the argument, as demented as it may be. a centralized version of this would be shut down in a heartbeat. a decentralized version running on a privacy-preserving payment protocol would be a different story...
