Auto-Retrieving Email Filters: A Counterattack Against Spam

This article discusses a novel approach to combatting spam: **auto-retrieving email filters**. The central idea is to use **spam filters** not only to identify spam but to actively punish **spammers** by overloading their **servers** with requests.

• The author proposes that **email clients** should follow links embedded in suspected spam messages, effectively launching a targeted **counterattack** against **spammers**.
• This approach aims to turn the tide of spam by leveraging the very volume of spam that has been its strength.
• By flooding spammers' **servers** with requests, the strategy seeks to disrupt their operations and make it more difficult for them to reach their targets.

The Mechanism of Auto-Retrieving Email Filters

The article details the proposed mechanism of auto-retrieving **email filters**.

• When an **email** is flagged as potential spam, the filter would automatically retrieve all the links within it.
• This retrieval process would be repeated multiple times, effectively overloading the **spammer's** **servers**.
• The number of retrievals could be customizable, allowing users to adjust the intensity of the punishment.

Benefits and Considerations

The article highlights the potential benefits of auto-retrieving **email filters**:

• The inherent passive nature of the current **email** system, which simply follows instructions, makes it vulnerable to spam. This approach seeks to rectify that by making the system more proactive.
• By actively punishing **spammers**, the strategy could deter them from sending spam, effectively reducing the volume of unwanted messages.
• The approach could force **spammers** to adopt more legitimate practices, such as including working unsubscribe links, to avoid having their **servers** overloaded.

Blacklists and Protection

To ensure that legitimate websites aren't targeted by the auto-retrieval process, the article proposes the use of **blacklists**.

• The **blacklist** would contain websites that have been identified as promoting spam.
• Only websites on the **blacklist** would be subject to auto-retrieval.
• The **blacklist** would be maintained by human inspection to avoid accidental inclusion of legitimate websites.

Addressing Concerns

The article acknowledges that the auto-retrieving **email filters** may not be a complete solution.

• Larger **spammers** may have the resources to protect their **servers** from overloading.
• The strategy may not be effective against sophisticated spammers who use multiple servers or have highly distributed networks.

Potential for a Shift in Spam Landscape

The author suggests that the widespread adoption of auto-retrieving **email filters** could lead to a significant shift in the landscape of spam.

• Spam, like other digital threats, could become a problem primarily for those who don't utilize proper protection.
• The strategy might force **spammers** to adapt their tactics, potentially moving away from mass-emailing and towards more targeted approaches.
• It could contribute to a more secure and spam-free **email** environment for those who adopt the new technology.
