Everyone has received unwanted forwards, chain letters, or urban myth emails. But unfortunately, when these come from your friends or co-workers, your spam filter won’t block them, and there is no ‘unsubscribe’ link at the bottom. StopForwarding.Us is a new site that let’s you battle this problem by sending a polite, anonymous email to ask your contacts to stop sending these types of unwanted emails. To do so, you simply enter the offender’s name and email address, and they will receive an email that asks them to kindly stop sending email forwards, and even provides some tips on email etiquette (such as “Avoid sending forwards to friends or relatives that you've grown distant with. It can be frustrating for the recipient when the only correspondence you have with someone is via impersonal, unwanted email.”) To prevent abuse, StopForwarding.Us will only allow one anonymous email to be sent to a single email address every three months. The site also has a small store that sells spam or forward-themed t-shirts and mouse pads, with proceeds helping to fund the site.
