Why isn't there an option for users to rate polls that other users have created? There needs to be a way to rate and add suggestions about which movies don't deserve to be in categories that they haven't earned.
Basically that's what the discussion threads are for on the IMDb poll board. You can't rate them but you can suggest and critique lists that are up for publishing. Each poll has a thread associated with it. It usually say's "discuss here" underneath the initial description and question.
