I tried to start one (really detailed, with everything concrete that's been released, dates and websites, all organized), and I got mixed up so fast. There are so many different articles where statements have changed over time, and there are so many different threads here. And now I'm just about to move. :/ If I get more time, I'll start working on it again. I do think it'd be really helpful.
Yeah, we should specify very NSFW before posting that link. Yes, that's her tumblr, but no, Heather is not in any of those photos. Tumblr is kind of known for photos/GIFs like that in that they're totally allowed (while they wouldn't be on Facebook, for example) so they make the rounds. But honestly, that's not that abnormal for a 20-year-old. It doesn't come across as "sick" to me -- it's just probably not something that should be looked at without being prepared because, obviously, not everyone wants to see stuff like that.
