So I could forge a bunch of bounces from somebody else's email account and
guess/use their ID in your table, and get them kicked off your service?

[that was light sarcasm]
You might maybe wanna use some kind of one-time token such as that
described on http://php.net/uniqid instead...
PS Yes, some semi-legitimate spammers will drop you from their lists if
you bounce email. The total scum spammmers won't -- Their return address
isn't even their own, much less something they check. I *WISH* all email
clients had a "Bounce" button to return emails as if they had bounced...
