Fake royal family?

[noblegiraffe]

I was just on twitter and a message of condolence to the people affected by the terrorist attack in Australia came up from 'Her Majesty Queen Dillys'. I didn't recognise the name so I followed the links in the profile and got more confused, then googled and even more confused.

There are instagram and facebook accounts. There are listings for several self-published books on amazon, goodreads and so on, from a variety of royal family members, and a detailed biography. But they don't exist?

Is this someone's weird hobby?

It's a weird hobby and some sort of parody

I kind of get setting up fake social media accounts, but all the self-published books? I'm assuming they don't exist either.
What do you have to do to get your fake books by fake people listed on Amazon and Goodreads?
