I (usually) don't even bother to go to that level. I just login to the account after resetting the password and change the email address on the account. If I can I close the account for good measure.
There was an Irish women's clothing site that I couldn't do that on though. I tried repeatedly to get them to remove my address and they assured me over and over that I'd been removed. Until they did their periodic restore from a backup and I'd start getting spammed with ads again.
