There has been a lot of conversation with some readers putting VERY negative reviews on some of the more successful indy authors' pages. I have seen it done to a few people now. It is not Amazon but Amazon doesn't do much to protect the author from such things and then there are some foolish authors who lash back at the reviewer which is never good practice. I was shocked when I started promoting on Amazon's forums and found myself in the middle of several arguments about indy authors and their "shameful self promotion." A big reason why I like this forum is that there is a lot of support and it is nice to have a reprieve from the trenches where I can say "hey, i got 5 stars" and get a pat on the back rather than somebody saying "well, let me just read your sample and trash your book based on the sample just so you lose your 5 star review."
Not that it happens all the time, but I have seen it more than once.
BUT, this thread is me being happy so I refuse to dwell on negativity
