I agree, you would be part of an anonymous group and that would be rather boring. To do any DC project, you should prefer to see yourself as a part of a team. As a "no name", you still complete WU's, but only as a group of anonymous individuals, rather than a large group, that has combined points and it doesn't isolate you for partaking. The only thing you can possibly gain from this is satisfaction for the help in finding a cure.
