You're a Collaborative Filter!

A collaborative filter, such as Cloudmark SpamNet, will let you join the hive mind of spam-bashers. The program's users report spam messages to a central database by clicking a button. As other users check their mail, the program filters previously reported messages.

Collaborationists who fawn over Google and Daypop love the participatory process even more than they hate spammers. But be warned: The program subjects you to group consensus rather than letting you decree what is and isn't junk for yourself.

In a past life you might have been:
A Bayesian filter
A Whitelist program
No filter at all
