One of the biggest problems with any kind of regulations concerning "spam" is that people define it very differently -- with the core definition tending to be "anything I don't like" which is rather difficult to reduce into written regulation. That problem seems to be cropping up at Michigan State, where a student is being disciplined for spamming the faculty. The student was upset about a plan to shorten the 2009 fall semester, and sent emails to 391 faculty members, alerting them to the planned change, and pointing out how it could impact their syllabi and schedules. Apparently one out of the 391 professors complained about this as spam, and the school notes that its rules say email to more than 30 people is considered spam (the actual policy seems to leave some wiggle room, but not much).
