As things currently stand, a mark completing a contract that was issued by an order for witnessing a defilement grants the mark no gain to mark reputation, and a minimal amount of gold (however much the Order chooses to offer). I don't really like this fact, as I don't see any difference between completing a contract for an Order and a person, but its not a huge deal.
The problem arises from the fact that, while you cannot gain any reputation for completing these contracts, if you happen to fail one, you will still loose reputation. This means that marks have almost nothing to gain from taking them, but everything to lose. Yes, these contracts do have some small gold reward, but these rewards are usually some negligible amount, and I know I can speak for the majority of marks when I say that none of us actually give a shit about the gold. We do it exclusively for fun, and to gain mark reputation for bragging rights.
Solution: we either need to allow these contracts to give reputation when completed just like any other contract, or we need to remove the loss of reputation when they are failed. Now that I know I can only lose reputation from accepting one, I know I certainly won't bother grabbing them until I have something to gain from it, and I imagine most other marks do the same.
