I really favor a zero staff time solution, meaning using spam assassin type daemons to kill the Viagra commercials, trying to *not* make eyeballing the actual content a part of any job description. Read on your own time, post at will, but as there's no censorship, no banning, life goes on.
As soon as staff becomes actively involved with content management, you've created a time suck, plus invited the term "censor" within an ostensibly free academic context. There's the potential for that to backfire, to reflect negatively on Drexel's reputation. At the very least, it'd be a newsworthy development.
