It's awesome that you want to help us remove incorrect alternatives. Feel free to report more applications below. But keep in mind that the only reason for an alternative not to be valid is if it doesn't share common functionality with System Ninja. It might not be a good choice according to you but it’s still an alternative. Read more about our thoughts about alternatives here.
