I have to worry.. I mean I don't have any knowledge on WHAT they were doing that was so deadly to the servers. It sounds like a threat to destroy FH and they've done similar before havn't they? What stops them now? I have NO idea what's capable of being done. Passwords are safe; thats fine and dandy, but what about the game?
As to the relevant post by DarkFurry, Akar reminds me of another user name on my friend list. Perhaps they have multiple accounts. I'd ban the IP adresses, but that's me.
