ChromaHost is just the hosting company. i.e. the company that provides the bandwith and computers for the site. The other stuff is domains by proxy, which is an anonymity service provided by Go daddy, the registrar.
You might be able to get a lawyer to put some pressure on Godaddy and ChromaHost if you can get one to write up a letter with the laws the guy is violating through his actions.
Chromahost is NOT just a hosting company. Notice how it resolves to a blank page??
Chromahost is owned by the gaming guy who also hosts on this server, but this is obviously a server mostly dedicated to dem sites. Maybe the guy administrates the server for them in exchange for hosting a few of his domains, but he ain't 'just' a hosting company.
I know hosting companies. That ain't one of em.
