“The Upside Down” name was stolen of my book at Amazon. This is copyright violation of my property. Somebody needs to answer for this, who?

So it was "invented" before the first release: Upside Down (1919).
Well... was it the next week after the day he had created the Earth and sky, or later?

Thank you all. I realize that I cannot protect that title by copyright, but I think what these people did is so immoral. They did not just copy the title. They actually hacked into my account and changed the password and took it as if it belongs to them. It feels like I have been raped by a group of degenerate, but I will survive.

I just realize that I can sue them, because it is not the title of the book, but the series title that they stole. The actual title is Blue and the Bonnets. The Upside Down is the series.
