Recovering 'lost' Blogger Posts?

I recognize it’s a nuts question; I’m asking from a place of samaritanism.

Basically, a woman called my workplace today hysterical from having lost her blog posts. She is still able to log in, but all of her (no doubt insightful and intellectually stimulating) material from the past three years has ‘vanished.’ Obviously if the server puked they’re just gone, but does anyone know of a situation where posts might appear to have been deleted and actually aren’t? Or have any other idea what might have happened? This happened a few days ago, if that’s relevant. And this is all the information I’ve got.

She’s obviously not very literate and I’m hoping it’s a simple misinterpretation that’s freaking her out. She sounds genuinely distraught (?) over it and I’d like to deliver some good news if there is any.
