This morning I read a news article saying Facebook had just bought Moves. Being a registered Moves user, I deleted my account because I'm not comfortable with Facebook having access to my location data.
In a mail they sent me, they assured me they had deleted my data and that my email address would also be deleted right after sending the mail.
48 minutes later I got a mail from them.

Previously I've seen unsubscribe emails that state you will have no more emails after those already 'commissioned' have been sent.
If they used a 3rd party service for sending out mass emails like that, they may provide the users in advance and have no ability to remove them last minute.
This purely speculation at a possible cause on my part though.
