If you use Linux or a Mac, run this command:
sudo bash -c "echo \"127.0.0.1 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 primedice.com
and Stunna's wrath will be instant and permanent
too I think.
Other than that, it's a good solution. Add any site name you want to be banned from to that file.
