I'm an adjunct now and was a grad student, and doing some of these things is actually dangerous: http://www.amazon.com/Blue-Angel-Novel-Francine-Prose/dp/006... or http://chronicle.com/article/Sexual-Paranoia/190351/. Most of the time of course they won't be dangerous, but it only takes one person to really fuck up a career.
Don't be so dismissive.
