Which is exactly why the DNS is the wrong level to do this at if you have a legal obligation to block access. The only way to do that is to block the packets themselves. Given these are gambling sites the chance of collateral damage is minimal if you just block all access to the ips in question. Just make sure you can get through to their nameservers so you can keep the list of IP addresses to filter current.
