I completely agree with you when it comes to pointing fingers-no one should be blamed unless there is definite proof of such.
But just one thing to think about. If it were your game server that was hacked and the hacker mentioned that FH was behind this, yet the staff of FH gives you info on the fact that they are not, would you not still take them into consideration for the sake of the safety of your game? Just because they aren't claiming your innocent does not mean at all that they think you are guilty.
If you are truly innocent, which I believe you all are, then there is no need for this argument to continue. With everyone's participation in figuring this out, we will come to the definite conclusion that you were, and are not, involved with the hacking. This just needs to be settled delicately, maturely, and in the friendly spirit our groups once had together.
Our games, FH, Moonrise, Cereal Soup-they are all monuments of how games should be online... families. We all care about our games and our communities, and we need to bring this emotion to the task at hand, setting aside game labels and working as one community as a whole.
