Dartmouth Dean of First-Year students Gail M. Zimmerman, in an email to students threatened with a lawsuit by Priya Venkatesan:

Questions arose as to our ability to block Prof. Venkatesan's emails. Whether that ability exists or not, it would not likely stop her emails from reaching your inbox given the dearth and ready availability of other free email systems such as hotmail, gmail, and yahoo.
Ah, yes. The "dearth and ready availability" of free email addresses. You never cease to impress us, Ivies! [Dartlog via IvyGate ]
