Dear Zooey: Anonymously report this prick to the administration. He's posting porn of students on his website? He's got some balls on him, I'll admit, but there is no way the university will smile upon this, even if he's actually tenured. And since he's stupid enough to post this stuff on the world wide web, nobody will know it's your fault that they caught wind of this sooner rather than later. BLOW UP HIS MARRIAGE AND CAREER FOR THE GREATER GOOD. He'll show his true colors then, and your friend will be no worse off than she is now.
