Now, on to the heads up for all authors.
The site ebooks-tree(dot)com (I am not linking directly so they don't get the SEO) is stealing work and using it to extort credit card information from people. They also have copyright works by many famous authors.
I have so far found 2 of my books listed there for download and a large number of my fanfics lifted from AO3.
Authors, go and check to see if your work has been stolen.
To get it removed you need to use this format:

UPDATE (15-Apr-15): All my works (bar one of my fanworks) seem to have been removed, so it looks like the process does actually work.
