There's no such thing as "double opt-in."
A request from some unknown location comes to you. That's not an
"opting in" because it is unverified that that is actually the target
You send out a request that the person whose address was the target
confirm the request.
Their reply to that is the *only* "opting in." Anything before that is
a random piece of data submission.
Calling it "double opt-in" accepts the spammer thesis that any address
they capture by any mechanism is an initial "opting in."
