This site did the same as any cloud mining site has, used BTC’s coming to show as if people are earning BTC by mining.
Server is located in the US and has never changed from the service hosting the VPS of this site since the creation.
Runs WHM and cPanel (latest)
Runs 2 mailservers 1 being a aussie landing page.
Runs a open MySQL database on the default port.
This more or less points to someone from Australia controlling the site.
Just a tidbit of looking into the site.
Edit: And the VPS service commonly allows spammers to use their service.
