As the unwanted emails keep multiplying with each unsubscribe, I'm trying two new tactics. First, if they give me the option during the unsubscribe to report it as spam, I do so; this may give them the understanding that I am willing to report them elsewhere and external pressure will be brought to bear on them. Second, I am putting each post into the junk folder rather than just deleting them. This may train the email program to recognize future iterations of the post, or the sender, and dump future posts into the junk folder without me having to do so.
