[Ovid]

I'm not going to link to anything for reasons which will be obvious, but basically, _why asked for privacy and someone doxed (outed) him. At this time, _why decided to vanish. I don't know that _why ever said why he vanished (he vanished, after all), but most assume that he left because he was doxed. This made Hacker News at the time and a follow up article about _why I read a couple of years later appeared to verify his identity.
