While you're correct in the sense that not all rapes end up with the victim and the perpetrator despising each other (many are between two people with an existing relationship, and he may have taken advantage of a situation they were in regardless of previously consented-to encounters), I think uid really hit the nail on the head; she's really going all in on this for someone that has so many allegations, but decided to speak to social media and Gawker before the authorities (ignoring the fact that she waited a year to do so, because in the off-chance that her claims are valid, these actions can damage/guilt someone into not speaking up until much later, if ever).
She's clearly mentally distraught over something, whether or not it actually relates to Arrington or if she's throwing him under the bus in some strange attempt to get/misdirect attention. It's unfortunate because these incidences of falsified rape claims are often leveraged by those that forget that these are the loud minority. I'm really hoping that's not the case, but even in a situation where she was not okay with his actions one night, she shouldn't have been sending him provocative photos the very next (I hope this isn't seen as victim-blaming on my part, since every situation is different and there's always the potential for Stockholm Syndrome-esque effects in these situations, I just don't think this is one of those).
The rest of her communications with him are clearly using him for who he is, and then quickly turn into spiteful posts when she realizes that she can't guilt him with sexy photos to invest in her and introduce her to others in the industry. Instead of informing him of being pregnant, she waits until the day she's "scheduled" to have an abortion to guilt him over it. Months later, when Arrington later asks if she wants to talk about it, she throws it in his face that she's "Facebook official" with someone "if that's what you mean", but is willing to meet up with him "as soon as possible" "near his offices" anyway (maybe in hopes someone would see them together).
On Scoble's status, she races to at the opportunity to insult another woman for being Arrington's new girlfriend (she isn't), drinking his "Kool-aid" and (if her claims turn out to be invalid) ironically accuses her of doing a disservice to victims of rape and abuse.
TL;DR, even if there's something remotely here for her to stand on, she needs some serious help. As such, I would absolutely call this evidence "damning" to the innocence/ignorance she's trying to portray.
