I use a catch-all and mark some handles as spam once a website has been hacked, or the email has been caught by spammers. I trust you've probably adopted a similar workaround for problem websites. For throwaway websites (where I use a password I have no intention of keeping track of), I often sign up as "spam@domain".. This is surprisingly blocked in a lot of instances.
