But how are the gaming/gambling laws in your country concerning internet gaming/casinos? Has there been established rules saying that they ARE illegal, or are no specific rules saying that they're illegal.
Because if it's ambiguous, I believe you could check if it's an IP block or a domain block. If it's a domain block you could simply use another DNS. There are public Domain Name Servers everywhere, you could do a simple search.

In my country it is clear that casinos are illegal so often the internet blocks gambling sites, but we can still access casino sites by changing DNS or using a VPN...(but I rarely use a VPN myself).
Again my country has never been blocked by some casinos or not blacklisted.
It's quite simple... if my own IP is blocking the site then the mirror link can still be accessed easily without the need to change DNS.
