To send them a new password when they have lost/forgotten the original one.
This is a one reason nobody seems to understand. And, of course, this feature fails for e-mail addresses where the account owner no longer has access to.
Another reason are deactivated/banned accounts - people then start to get into contact with board administrators thru e-mail (no pun intended) and demand reactivation/getting unbanned. But their e-mails come from an address that doesn't match the one in their account profile. The problem? Anybody could state he "is" the account owner and write such an e-mail from whichever address he wants. However, if the e-mail comes from the same address that is setup in the account details then it's halfway a proof that the actual account owner has written the e-mail.
It doesn't have to be an e-mail address, it's just that almost nobody has an idea to provide an actual way to contact him once problems emerge. If you want to provide only a Twitter username then that's fine, too. (E-mail is one of the few ways that could be encrypted and/or signed, but apparently that's not valuable to anybody starting to argue about e-mail addresses.)
"Oh, that's too much of a hassle, I just signup anew" would most people think. Until board administrators who forbid this find out.
