I did block her, and she "hired" people to flame my story. So why bother blocking her at all? I decided to confront her on
my review board and expose some of the major inconsistencies of her "crits". Several people have inboxed me over what I said to her and have thanked me for saying it. She's infamous for making people stop writing and she's making an already slow fandom on FFnet slower - and many are going to AO3 to avoid her flames. Since I publicly refuted her, she hasn't reviewed again. But she's still bullying other authors.
I don't need to name who it is. Reading through my reviews, you'll see her. Clicking on her link will take you to some nasty, homophobic and racist commentaries and some really disturbing ideals (not to mention incorrect assumptions about fanfiction writer's rights).
Since the 2012 purge of FFnet, more and more users are going to AO3. They have the potential of overtaking FFnet's popularity and I hope they do. For the way FFnet's mods have been treating writers on their site - as Violent Crow said, deleting stories for so-called abuse when there isn't any - I'll be surprised if FFnet manages to still be king of the Fanfiction in a few years. I'm predicting AO3 will surpass it.
