My solution to this problem is, while continuing to use unique email addresses for each service, to just put a short random string of letters before the @ instead of the service's name (e.g. jcnclp@example.com instead of hilton@example.com). They're all just stored in my password manager, so I don't need to remember what address I used for what service.
