Taking down the hoster is only a short nuisance for the fraudster. He'll hop to another hoster and point the domain name to the new one. Nothing changes.
Unless the scammer has no backups, but any competent scammer would.
Tucows is the registrar for Njalla, one of the "privacy-focused" domain name sellers (they are not authorized to register domains themselves), but they chicken out and suspend domains as soon as you report them.
I am saying this because Tucows probably makes them do this or else they terminate their contract with them.
It seems that Tucows won't do anything unless threatened with legal action.
