This is just anonymizing of addresses. Through your throttle account, connected to a convenient browser extension, you can conveniently generate throwaway addresses which forward to the real inbox. These addresses can be shut down and since they are unique, they identify misuse.<p>Anonymizing isn&#x27;t new. For instance Craigslist generates an anonymized e-mail address through which people interested in your ad can contact you. (Of course, if you reply to it, then you reveal your real address.)<p>People who run their own mail domains do this kind of thing on their own.<p>I have the following system: the local part of the e-mail address has a four digit security code. If I give such an e-mail address to some vendor, it serves two purposes: the address bypasses spam checks, so I&#x27;m sure to get the e-mail. (Usually transactional e-mails are important and not easy to re-send.) Secondly, I can change the code to shut down senders who abuse the the address.<p>Some banks offer throwaway one-time-use credit card numbers linked to your real credit card. That is very similar to this.
