Community filters
The admin of the student email system related a tale the other day that I found interesting. They use dspam for their anti-spam needs, and it has a Bayesian filter. It also has some other features which have, as I said, interesting side-effects.
There is a local independent movie theater that sends out a newsletter. Some students have plonked the newsletter into Spam rather than unsubscribe.
The dspam system is configured so that if enough students mark a specific sender as spam, then that sender is blacklisted system wide.
You can see where this is going? I thought so. Enough students have reported this independent movie theater's newsletter as spam that the whole system now blocks it, and we're getting reports of 'false positive!'
