I've seen yet another variation on this. Sites that recycle usernames,
particularly common at schools it seems. User X s*bscribes to my list
and never uns*bscribes even though he no longer has the account. Next
year user Y gets assigned the same account and is befuddled by all the
incoming mail. "I never asked for this" is in this case a true statement.
I've gotten the snotty cease and desist letter from the site's almost
equally befuddled sysadmin who is certain his user is the victim of a
s*bscribe forgery. When I write back that this was their fault for
recycling user names and include a copy of the original user's s*bscribe
request with a year old date attached it seems to work an amazing
attitude transformation.
