The service's 475,000-plus members contribute by "voting" on what's spam and what isn't, using the BLOCK and UNBLOCK buttons that the SpamNet program adds to your Outlook task bar. Enough votes from individual members and a message is blocked for all. With thousands of reports coming in every second, it can be pretty effective.
