You can disable your spamgourmet account by setting the forwarding address to be blank and saving. As a matter of policy, we "retire" all usernames to prevent future users from receiving email that was sent to previous users.
As a precaution set your prefix (or add a watchword) that is large and random, like "dfygmuiodtt" to effectively disable the creation of new disposables on the account.
Real programmers don't comment their code. It was hard to write; it should be hard to understand.
