phane invited her.

They were also invited over a year ago. Things were a lot looser then. I'm sure you could find dozens of other similar users. It's not against the rules, really, but proper etiquette (nowadays) would be to go with privileged.
Edit: Actually, I should say they joined over a year ago. So the invite might have been much more recent, I'm realizing. Did it just happen? For someone who doesn't upload, there's absolutely no difference between privileged and contributor.
