This x100. If you have no followers and no one is re-tweeting your vitriolic slime, why should twitter care, they simply want you to stay on the platform. Now if your circle has reach and you are a known public name, they must act as if they care. They play politics to please the masses, without subjecting the masses to the same politicking.
