about the first one: that's why utopian mods should have a trained eye and spot stolen work when presented, there's always someone who tries to cheat, I think one attempt and permanent ban should weed them out.

I agree that the second one should explained thoroughly, I don't think that users should mention utopian when they contribute to a project, they should contribute like anybody else, when they got positive result, they can think about reporting to utopian, the goal is relieving the utopian moderators from: having to check if a contribution is useful or not so they can focus on eliminating abuse.
