I'm checking every day to see if that nasty person has been trashing the story again. Whoever it is doesn't have enough courage or decency to write a review, they just manipulate the rating system to trash the story.
This would be considered Spamming on FF.net and Sycophant Hex would ban anyone who did that from all their archives. The Petulant Poetess wouldn't stand for it either. In their policy FicWad states that they won't stand for plagiarism or harassment. This is certainly harassment, in fact it's the only type of harrasment possible on FicWad.
I'm beginning to think that this person's motive is jealousy; you can write and they can't, so they trash your story to make them feel better. That's a result of the idiotic 'Self Esteem' curriculum that has run rampant through the schools for many years now.
Aren't you glad you were out of school before they started teaching that curriculum? I sure am, I was taught that self esteem comes through what I achieve from my own efforts, not just because I exist.
