Yes but that's a huge amount of work, and is not the 'fun' part of coding. It's one thing to have to spend those cycles looking for errors or incompetence, and hopefully helping the contributor improve their skills so they can in turn help the project more in the future. It's quite another to spend even more energy being suspicious and looking for subterfuge from someone that has been one of your most helpful contributors.
