I think most of us who knew sorta tried to brush the whole thing under the rug because we didn't want to make a spectacle. We have no idea who it was for certain, we have no idea if the persons personality was real or pretend and just the names and faces were a pretense, we have little to no idea why they did it, or if they'll come back.
The most commonly accepted suggestions are that the person was a girl, who wasn't malicious, but also didn't want to be herself and used a false identity. I can understand that, even I was deceitful when I first got this account (emilio and tommy fucked my shit up! jerks!). Of course, it's possible that the person had different reasons for it altogether and was malicious, but I don't feel comfortable making those sort of assumptions. Aside from some feelings of betrayal for the deception, there was no harm done. Except the naked pictures some of us sent will probably come back to haunt us.
