Yes, I did that within the past few days and was quickly unsubscribed. But
the last time I did this I replaced the last 12 characters with the phrase

So, you should not be posting those confirmation codes!

Is it difficult to verify that the unsubscription and resubscription
processes of 0xloem at gmail.com today were normal?
With 0xloem, I posted no codes and did not find a farewell notice in my
