Years ago (> 10) I used me+hertz.com@mydomain.com registering for Hertz. I started getting spam on it. Tried contacting them to let them know someone was selling customer email addresses and of course they just responded that obviously I had a virus or something. Mostly unrelated, but just before I responded I was modifying a custom milter to filter messages based on the byte string "Copyrights =C2=A9 Xsolo All Rights Reserved" because this particular spammer likes to copyright his gmail spam. Weird but convenient.
