Back in simpler times, I set up some mailing list software and added any spammer that found my inbox to that list, then injected their spam back to the list. This was when the majority of spam was sent from real accounts. From fields were not forged, generally.
There were clear instructions in the email headers on how to unsubscribe.
The indignant chaos of them fighting with each other demanding to get off the list and to stop sending them spam was priceless entertainment.
