_why's account on github has always been "why", presumably because github does not allow an account name to start with an underscore.

_why deleted his account and somebody snatched it up real quick

Also, the only current repo in this account (now called "because" and not "lol" anymore) has been CLONED by two other people! They made some commits, even. wtf?

The new /why account is a placeholder. The because repo is a thing that says some things about _why, stuff like theories on why he might have done it. Not a hack. (although I'm still not sure about the 'lol' thing...)
