Have a single "I clicked by mistake" button that resubscribes instead.

Yes, the automated system prefetching links will always click said button.

Not if the button issues a POST request.

The button I was responding about was an "undo unsubscribe". A bot won't click that button, but may follow a link.

Right, I assumed the button would be linked from a subsequent email confirming the unsubscription. You're right, a button in the unsubscription page doesn't help.
