Number of book giveaways on goodreads decline rapidly

Due to unknown reasons, the number of books in the goodreads giveaways have declined rapidly for indian users. There are almost no indian authors who have launched their give away on goodreads.
A year ago, there were many indian authors who listed their books on goodreads in giveaways , in February 2018 the number of authors and their marketing teams has declined rapidly.
Any information on the reason for the change will be greatly appreciated
