Around the same time, or maybe even earlier, some random company sent me a junk fax every Friday. Multiple polite voicemails to their office number were ignored, so I made a 100-page PDF where every page was a large black rectangle, and used one of the new-fangled email-to-fax gateways to send it to them. Within the hour, I got an irate call. The faxes stopped.
Circa 1997 a coworker lamented that he had signed up for some email list, and attempts to unsubscribe weren’t working (more of a manual thing, IIRC). I made the suggestion to set up a cronjob to run hourly, to send an email request to be unsubscribed. It would source a text file containing the request to be unsubscribed. And with each iteration, it would duplicate the text from the file, effectively a geometric progression. The list owner responded about a week or so later, rather urgently requesting that my coworker cut it out, saying that he would remove him from the list. Apparently the list owner had been away on vacation the entire time.
