Sorry, I may not have been sufficiently clear, you&#x27;d register a new throwaway gmail address, and then create forwarding filters based on throwaway+alias. At that point, it doesn&#x27;t matter if $badsite strips the +alias and learns your email is throwaway@gmail, you&#x27;re not forwarding mail sent to that address anyway.<p>Anyway, I&#x27;m probably going to register a throwaway domain to use for disposable email per my final suggestion, so thanks for the post!
