I think trying to find her is idiotic. What are you going to ask when you do find her, 'Hi, are you Cracky?'. And what are you going to do when you do find her, to anyone who is looking? I think this is a case of not planning ahead. The poor girl's probably scared to death of you guys so it's not like she's going to admit she's Cracky.
In the case of just 'accidentally' bumping into her if you go to where you suspect she lives, will that not seem odd? Could you honestly strike up a true conversation with a woman who looks like and you suspect to be Cracky, without feeling disillusioned and guilty about your motivations? Oh geez, so many questions to ponder.
I would like to find her also, at least to find out how she is, but that's about as far as it goes. Now thinking ahead and physically trying to find her, it wouldn't be wise.
On that topic, you'd think as many people that may come across her daily, in school or otherwise, would come out and say just for a chance to win the internets for us and some 4chan members, and to chat it up. I'm sure anyone that knows her may know about her popularity with 4chan because of how word spreads and new pictures of her leaked. Anyhow, she seems to be doing a good job of being anonymous the past year and if the solace makes her happy, I'm all for it.
