Do you have any proof of this? I'll call GoDaddy up right now and let them know that a site on their network is distributing pirated software. I've also heard the clients they're distributing might be infected with malware (i.e. the kind that turns your computer into a zombie which is then used in DDoS attacks like this.) GoDaddy will shut them down immediately. This info could also probably be used to get Viasite to shut them down as well.There is discussion that the site is giving hacked clients to people to they can play Minecraft. I am sure Mojang would care since it is hitting their wallets.
If anyone can find some proof of this I will give them a generous reward.
