How is that a fact? Wouldn't that be an opinion because it can't be really proven because what not good for you, might be great for me.
Other then that.. I have no comment, except the owner of the hack from what I read on his post did seem to try and give you your money's worth, and I don't think he is at fault...
And.. about the mention if you can't get on. I personally feel, it's not about getting personal or what not... a simple "hey, i won't be able to get on the internet much for awhile" I see as prefectly okay. That way you are not accused of ignoring a client if we want to call him a client, and you don't release any real personal information...
