First, the situation with the tweeter, Eunice Beckman. Tweets began on 3rd March 2020. To date, 800+ tweets have been posted. That’s 800+ books linked to the we-books.ga site. See the screenshots that follow.
I haven’t checked out all the books offered free for download, but those I have are, like my own Lake of Dreams, available only on pre-order. Now isn’t that odd?
The link given in the tweets goes to we-books.ga. See the following shots. Yesterday, the Contact Us button on we-books.ga site linked to ReadEveryBooks.com.

They searched the web and couldn’t find? No, a search would have delivered them to this blog, my author’s page on Goodreads, and the Kindle Store on Amazon

The link here went to ReadEveryBooks.com Note the variety of formats available

No comment required!
Yesterday, the Contact Us button on we-books.ga site linked to ReadEveryBooks.com. I tracked them down to their service provider and reported their scam (piracy, copyright infringement and phishing).
Today I find the thread regarding my book is closed. See the pics below.

In case you can’t see, for it is small, Caffeine, a Senior Member, says CC just to make sure you aren’t a bot. And the last post on the thread: Thanks guys, was waiting for this book long time too. (I should be so lucky!) She really ought to have gone to Amazon!
And the Contact link now delivers the enquirer to talecrate.com

Talecrate was registered in March 2017, has a UK tech contact and a most interesting Hosting History: 3 changes on 4 unique name servers over 3 years.
I checked out talecrate. See the pic…

Job done. Warning given. Please do avoid.
And once again, this evening, the link takes gs the enquirer to ReadEveryBooks. Somewhat erratic in the addresses!
