"Attention whoring" is just a horrible and overly-exaggerated term imo.
The way I see it, mkkmypet shouldn't be getting slammed for this so much simply because of how tight-knit a community GW is. Posting this on 4Chan or some BIG FORUM where no one knows anyone would be the equivalent of walking around with a bulleted list as Steel said, but I think this is a little different.
However, if this internet medium of expression worked in such a way that people couldn't reply to your post (aka some sort of ANNOUNCEMENT system) you could argue that her telling her story was an emotional catharsis of some sort that she was extending after going to a psychologist and telling family, friends, etc. In that case, since no one can reply and say "omg SO SORRY :teardrop:" there is no yearning for attention, just for catharsis.
However, when you don't hesitate for a second to post your life story of sexual abuse on this internet forum where people you don't know are quoting it and sayin "thats horrible!!!! i hope ur ok" i think it's hard to deny that there is at least a very small part of you that is secretly hoping at least one person will read it and give you e-sympathy.
I mean, if this was JUST supposed to be some sort of emotional purging then why couldn't you just write a short story or a poem using other people's names KNOWING VERY WELL that you are writing about your own experiences. Or make a note on DeviantArt or LJ and LOCK COMMENTS. Hey, i mean your story is getting out to internet people who aren't complete complete strangers ("sweet.... the guy who thought my drawing of Kefka was brilliant is reading my story :p ) but there is absolutely no intimation of a need for attention because it's LOCKED and/or you're not paying attention to the comments!
