I am not familiar with this particular site, but the general idea of an "assassination market" is that such a market is "actually" a dead pool where all participants are guessing when somebody will die, and anybody who guesses correctly gets the payoff (or a share of the payoff, if there are multiple winners). A dead pool 'becomes' an assassination market when the dead pool participants realize that by being an assassin, they can accurately guess when somebody will die. So, in an assassination market set up this way, the prize does not necessarily go to the assassin. It just goes to whoever correctly guessed the date of death. If the assassin puts money down on April 15th, and I do as well, then the assassin would get half the money and I would get the other half, even though I had nothing to do with the assassination (besides in part 'funding' it. Also "half" assumes that both I and the assassin put the same amount on April 15th...). The problem of other people besides the assassin winning money isn't actually a problem, it is just the system working as intended.
