Maybe she doesn't want the general public to keep up with what she is doing.
If I recall, one of the incidents that 'freaked her out' was someone recognized her, and came up to her on the street. Now that she has a youngin, she wants to put the chances of that happening again behind her, ergo the ban on pics. Wouldn't blogging regularly about what she is up to be counterproductive to discouraging people from coming up to her in the street?
