I think you are to be commended for sharing with others what the problem turned out to be, having started the thread.
Doing that takes a certain degree of integrity and I'm impressed with your honesty and candor. A lot of others might have just protested that they were unfairly treated and left it at that.
You are professional about the situation and show respect for those who replied to you by posting what you now know to be the source of the problem (and not blaming DH for it). Your doing so will very likely spare others the same frustration and confusion you experienced.
It's unfortunate that it ended the way that it did; I think I understand what you were thinking when you put in the fake address. I suspect that, in the past, many of us have done the same.
Times appear to be changing, and it seems that many online service providers are now a lot more careful about being able to place a "real" name/address to those they provide service to, and we are just going to have to live with it or get a lot more sophisticated ourselves.
I hope you find a good home at your new host, and wish you the best of luck with your blog!
