I emailed her at the start of summer, and didn't get a reply til months later! When I saw Maggie she explained that she had some personal matters to deal with which was why she didn't work for ages. It wouldn't surprise me if she's had to give up her escorting career (albeit temporarily) again to tend to her matters once again.
I was lucky to see her as it appears she only returned to work for a couple of months, and as you say she hasn't logged in since Christmas. But send her a message on AW, she will respond when she returns to work.
