Hello; I have run into a strange problem. Someone at another organization claims that someone else keeps subscribing him to all of the Listserv lists hosted on my system. I have never run into this problem before and I am unsure exactly what to do. Obviously, I need to delete this unwilling subscriber from all of Temple's lists, but I am not sure how to do that. My attempts have so far failed. I figured that in the worst situation, I could just write a Rexx program to quickly pipe in each list's file one at a time then send them back to Listserv, sans the unwanted subscription entry, for processing. I am hoping there's a command to do this instead though. I would like to track down who is creating these false subscriptions, but I simply don't have time. The person who is the brunt of this prank is also not at all forthcoming with information that could help me be a detective in that regard. So far, all he's done is threaten to lodge a complaint against my employer with the Internet. As such, I only feel obligated to filter out this individual from all lists here en masse. Does this seem reasonable. If so, what's a good way to do it?
