A DKIM-signed submission request? With IP, time stamp, and such like would be pretty undeniable intent to subscribe, IMHO. Or provide plenty of fodder for the sysadmin of the domain in question to track down the imposter.

What sort of "proof of opt-in" could they provide that can't be forged? Also, it does not follow from that requirement that senders must be "identifiable." That may be a separate legal requirement, but it doesn't logically follow from the opt-in proof requirement. I also do not see how this matters when it comes to blacklist operations. "Tell me who your customer is so legal action can be taken against them" is what the law you cite seems to amount to. You are perfectly to block or blocklist anyone you want no matter what the law says.

This is exactly the problem. Privacy Laws in Switzerland (and most other countires I know) states, that the sender must provide proof of opt-in. Therefore, the sender must be identifiable. If the sender is not identifiable, the ISP of the sender must provide the identity of the sender. So an ISP does not face any legal liability on providing the identity of the sender as this is a legal requirement and the ISP acts according the law. There are court cases confirming this procedure. If this procedure and priority of privacy requirements is not observed, a spamer can never be prosecuted or blocked. The spamer can just pretend, that all his addresses are opt-in and that he acts legally but never has to prove it. Therefore Mailchimp cannot block him, or he can request to be unblocked because he claims towards mailchimp, that the spam reports are wrong and he has proof of opt-in from the recipients, which he never has to show anyone. The spamer could probably even prosecute mailchimp for blocking him or canceling his services. The users of our Blacklist request that we block mailchimp for not respecting privacy laws and not providing the legal identity of the spamers so they can provide a proof of opt-in or be made liable for not respecting the mass advertising law. So, do you have any suggestions on how to solve this issue?
