I had to go through the subscription process to do this for both
gmkarl at and 0xloem at . I was getting bounces, earlier, in
response to emails from both email addresses.

I'm not seeing this.

However, when I looked just now, my client misbehaved, mutating folders on
its own. It's been doing that rarely for years, though. It is possible that
somebody used access to my email account to unsubscribe me, and then
covered their tracks. But it's concerning that this happens at the same
time that others are getting unsubscription notices.
