I've written recently about Goodreads' brand new policies meant to protect authors and reviewers from each others' sharpest fangs. But Goodreads isn't the only place an author can step in puddles.
Today I read an amazingly thorough blog post by Anne R. Allen. The Laws of the (Amazon) Jungle- Eight Rules Authors Need to Know to Stay Safe is essential reading for those of you who have questions about balancing etiquette with marketing.
Including: where to report abusive postings on Facebook, Amazon, Goodreads and Twitter.
Good luck out there!
