Update - it seems like IJJI.com has been hacked about 4 times now, each by different groups. As of this update it directs to DXT gaming (http://dxtgaming.com/) All I can say is iJJi is getting owned pretty hard, you would think that they would have some sort of protection for such a sophisticated gaming network but instead they've left themselves vulnerable to many attacks. Let's hope the sites DB or any personal information wasn't extracted. Just goes to show not every site is safe from attack.
Some are saying it was an ex-webmaster but nothing has been confirmed atm. Either way props to the group and hopefully this will be a lesson to Ijji to fix up their security.
