Taken from the Primedice thread, if you want to ban yourself from a website please follow the steps listed below:
I have messaged stunna countless times since months now to IP ban me from he's website as I have a some how sort of addiction to the game. Whenever I get bitcoins, I usually lose them to he's site and all he does is ignore the request.
I feel that this is extremely imature and that a gambling website should not treat their customers like this, he talks all about playing fair and everything but when a customer can't control he's self and its behind the scenes from the public. He doesn't give a shit basically if you lose, just ip ban me already jezus.
If you use Linux or a Mac, run this command:
sudo bash -c "echo \"127.0.0.1 www.primedice.com\" >> /etc/hosts"
Stunna hates what you do that shit, and will instant ban you.
In Windows, the file is at
c:\windows\system32\drivers\etc\hosts.txt open it as an admin and append the line:
127.0.0.1 www.primedice.com
and Stunna's wrath will be instant and permanent
