I agree on part one! you would need to do multiple things though, separate the sponsored ones from the non as they have an advantage.
Blind voting!! as in, people can't view the poll until after they vote or else people will vote the already winning mod.
Have the rules state that RHR may use those build pics everywhere as that would be great publicity
Part two, that will be hard as you'll need someone indifferent to keep an eye out on every post
