Occasionally, I've had a few Amazon reviews deleted from each one of my books and they seem to occur randomly. As far as I can tell, I don't personally know or have a social media connection with the ones that were deleted, but I could be wrong about that. As an indie author, it feels frustrating to work so hard to get reviews and then have them mysteriously deleted without warning or explanation from time to time.

Another thing that puzzles me is how Amazon calculates my average rating. I've had a handful of 5-star ratings this year (mostly verified or VINE reviews) and it didn't change my average rating at all. That seems odd to me. A true average would be more accurate in my opinion... even if it is a true avg. of verified reviews only.
