It's doing the rounds again. Sigh.
For anyone not aware, it's a chain thing typically circulated on Facebook, and tells you that you can get up to 36 books just by sending one book to someone else. But no, it doesn't 'work'. The vast majority of people who join in will not receive any books in return. And if you are one of the lucky ones who did get lots of books, well done on scamming your friends.
Books are great. Giving books to people is a Good Thing. Scamming people isn't. That is all, thank you.
