Comment 16 for bug 341935

So login will happily send you as many confirmations as you request, each with a different token. If you're trying to log in more than once it's probably because you haven't gotten the confirmation message. We really need to rate limit that. A simple approach would be if we already see you in the pending set, we would direct you to answers or feedback for more help. (And perhaps not send you another confirmation, or rate limit it.)
