I believe many humans have issues with DCMA in particular on YouTube which seems only too eager to block content that is subject to a DCMA Takedown Notice.
The only thing I noted in your review was a large number of quotes from the book, that could have triggered the action maybe.
Anyway now the publisher is ***ked and can't ever remove the review thanks to Steem blockchain, great idea to repost it here.
It was a very positive review, it is very weird to want it removed.
You got an upvote & resteem from me.
Steem on beyond the moon, we will all watch it go way past the moon. Good luck to us all.
Could be or it could be the images of the book, either way it is still fair use and a common practice with reviews.
