I've reviewed several books there in the past and had to delete my review completely (and the book from my shelves), wait a few weeks, and readd the book, sans review. With some authors (and it was always men with me) it seems like they feel like since it's not "your space" they have the right to comment because Goodreads is "shared" space, unlike a blog review. Goodreads has not handled the breakdown between author/reader very well and most of their efforts to discourage this behavior in authors seems to be restricted toward finger-wagging warnings rather than firm policy that they'll risk their account if they use their position and social capital to hassle reviewers. They do have the "do not allow non-friends to comment on my reviews" setting which I started using last year. It doesn't help if it escalates to Twitter, but at least in those cases it's easier to block/mute folks and pretend it's not happening while the Goodreads account itself stays functional for people you've friended to talk about books with.

The breakdown of the wall between author/reader and the continuing investment of authors into their own publicity continues to cause problems and really worries me. I keep my text reviews in space I fully control these days because it's impossible to know which authors are going to get angry and poke me over my criticism. Really sorry this happened, because however minor it is it really just amounts to being told that your feelings and experience with a story are invalid and an excuse for insult slinging/abuse. That crap is exhausting.
