What
@RoyalOffshore said is totally right.
You can have a domain in Namecheap (< for example), all your data and whois information are stored in Namecheap Servers and database.
If police or law suit want to catch you, they will use tools (DomainTools Whois History) is a good tool to see where you have been registrated with domain.
They will follow, they will investigate who is behind the domain in XXXX Year. The owner and all details behind the domain.
If you transfer to Njal.la, you will be "Anonymous" for some Anti-Piracy Groups, but if they have court order or police are investigating you.
The FIRST thing they will do, is searching for old data like old Whois History, old IP History, reverse whois etc.
If you want to make you "Anonymous" you will need to register a new domain, is better and much more secure than "keep with the same" like I said there are records behind.
For example if you are in Hosting that is not offshore, your IP is exposed probably you will be recorded in IP History from a domain and others tools.
You need to register a new domain, pay with cryptocurrency like XMR or Monero, and you will be more safe than before.
There are plenty tools to discover > who is behind a website. Also some of them are TOTALLY FREE, others you need to pay to have full access.
You can be traceable if you use Njal.la, Cloudflare are now giving details Info, IP address is not secure anymore. Is good only to hide your IP from server.
But with court order, they will give your login IPs, timestamps etc etc etc...
You must configure a VM encrypted and use VPN to access all things, never login with VPN your social media, personal email etc. You never will know if a VPN is logging or not. So probably, you need to make sure, you don't do shit like this one.
Njal.la is the best, cheapprivacy.ru is good alternative, xuid.ru is another one.
**Keep in mind, you can still be traceable it depends on the country and what you will do. My friend if you do something very illegal, forget. You can be jailed for years, if is something "low" and not HIGHLY illegal, you will be fine until you reach the top on the mountain.
When you website is being famous, you will be in trouble trust me. When you website is "medium" or not so famous, the troubles are much more less.
