Is a picture needed?
I have a character idea based on an old spambot from 4chan. It was this Picture stolen from suididegirls that was horribly corrupted with .jpg artifacts. It kept posting with these ridiculous fake responses "Thanks OP I come on cat, it his at penis" like some digital equivalent of the Saigon Whore From Full metal jacket. Eventualy 4chan implemented a capacha which finally put her out of her misery, but the whole time, I couldn’t help but anthropomorphize it and feel sorry for her.
My idea would be a corrupted program, a failed (Pre ISO) experiment, Perhaps by Flyn or CLU, to create a perfect digital life form. The experament was considered a failure and she was supposed to be Derezed. However it turns out they accidently made her immortal and capable of recreating herself from backups imbedded in junk data hidden in the Grid. Each time she dies, she comes back, but each time she comes back, she gets more and more corrupted.
She makes her living as a Spambot/Hooker and is trying to find out a way to either get back all the data she has lost with each derezolution, or die permanently, ending her suffering.
