I'm a bit sketchy on the details, but apparently it went down like this (and someone, please correct me if I'm wrong about this):
The reason Anna doesn't try to help Chris is that she doesn't give a fuck about Chris.
Anna originally came here to the Farms (back when it was the CWCki Forums) hoping that the userbase would appoint her queen of all trolls and kiss her ass because she was so good at getting herself into Chris' life. Rather than praise her for being the most A-list of Chris' trolls, the bulk of the userbase told her to fuck off, because Chris' trolls are a dime a million. At this point Anna tried to take her ball and go home, ingratiating herself into Chris' life and using her relationship to him to try to specifically fuck with us. She has literally never cared about him beyond her own ability to cynically manipulate him, and mostly dedicated herself not to helping him, but fucking with our ability to cover him however she could (resulting in this emoticon:

).
There's a contingent of sad fucks who basically appointed themselves the arbiters of Chris content and tried to gatekeep it; Anna was one of the first (and most obnoxious) by my understanding.
