If there is a rogue actor on the internet, even at a large scale, the rest of the Internet blackholes their traffic, and treats them as a failure point. Various routing tables are updated across the internet to not consider them a viable destination or source, and traffic normalizes without them connected. It isn't the action of one central authority, more a natural response to failure by separate parts of the internet.Its akin to shoppers and suppliers refusing to go to a particular store anymore. No one shuts the store down, but it no longer has products or customers.
