Reader, Writer, Merciless Reviewer and Incurable Romantic
Bots and Spammers are routinely purged.
And some authors are bitching . . . again.
Halfway civil discussion here:
Including the observation that it may not be a direct connection between that author and that reviewer that got the review(s) removed.
Slightly less civil discussion on Twitter (no link) because, you know, authors NEED those reviews and so it's OKAY to interact with readers and ENCOURAGE them to leave reviews, just like it's OKAY to swap reviews with other writers who are FRIENDS.
