A Community Approach to Blocking Spam |
How Can a Community Block Spam? We are an anti-spam Community of over 10 million people in 160 countries that work together to block spam. Each user who reports spam to our database of known spam creates a "block" for that message to all other users worldwide.
The average user reports 2 messages a day to our database. A simple click, click. However, multiplied 10 million times, creates over 20 million spam "blocks" per day. That is about 1 million "blocks" per hour, enough to stop most spam outbreaks in 30 seconds to 3 minutes. |
Who Are the Spammers?
Spammers are advertisers, phishers (thieves) and viruses that send copies of themselves via email. Spammers are "successful" when a very small fraction of the recipients respond to their email, accidentally give out personal information or launch a virus program. To reach the maximum number of people, and maximize their results, the spammers send the same message to millions of email boxes.
People are Excellent at Spotting Spam, Far Better Than Computers
Because the same spam message lands in everyone's box, only one person needs to report the message to the Community. So, each of your reported spam messages to our Community can instantly help millions of other people in the Community by blocking that message from their mailbox.
How the Community Works Together for Maximum Blocking
The Community is composed of millions of individual users who receive millions of email daily. When a spam message is reported by a Community Member, the message is sent to a central database that records the spam. When the other Community Members open their email, SpamSentinel checks the new messages to see if it contains reported spam. If the Community had identified the message as spam, SpamSentinel redirects it to the Quarantine.nsf database. Today, their collective reporting power captures over 99 percent of all spam sent out on the Internet.
Trust the Community
To ensure that each Community Member only reports Spam, each participant is ranked according to the number of good reports they have made.This trust system is critical. Community members who vote with the Community have a high rating, and their votes count. Spammers who falsely pretend to be part of the Community, and who vote against the Community, have a "negative" rating and cannot influence the outcome of the vote.
Near Zero False Positives
It takes more than one person to block a message, and that person must be Trusted by the Community. Therefore your personal or business email cannot be blocked, as it cannot be received and voted on by multiple trusted Community Members.
