I know 12 year olds who look up creepy-pastas on youtube that are more disturbing than that avatar.
Can't say about the story, since I never read it. I HAVE seen stories on here in the past that contained actual sex-scenes and somehow were 'ok' because they had a disclaimer and warning beforehand. So yeah, that was a thing at one time... didn't agree with it, but it was allowed. *shrug*
This just feels like a witch hunt. And honestly, after catching up on things I missed while being gone, I'm a little wary of the justice system around here.
But this? It's a vampire troll-face. Far from the worst the Internet has to offer.
