If such a process existed, the entity in question would almost certainly end up being shut down by that process, unless they find a funny technical loophole around it, in which case that would be a failure of the law that should not be rejoiced by anyone.
But as it stands, that law and process does not exist; ISPs already can and will shut you down for things like downloading copyrighted content (with or without complaints from the copyright holder), tethering without approval, being a technical nuisance in the form of mass port scanning, hosting insecure services and other such stuff. "Hosting a platform solely dedicated to harassment and stalking and ignoring abuse complaints about it" absolutely deserves to be on that list.
