Is this not the same as the new "spoofed subscription" feature of 1.8c?

Excerpt from the maintainer's release notes: Starting with version 1.8c, LISTSERV is now able to detect these "spoofed" subscription attacks automatically. When more than 50 subscription requests are received from the same account in a short time frame, LISTSERV automatically undoes all the subscription requests and rejects any further subscription attempt for a certain period of time. This applies even to requests that LISTSERV forwarded to other servers; LISTSERV will then send a SIGNOFF request to the remote server for the address in question. Note that, in some cases, the subscription may not be undone, either because of a temporary condition (locked list, etc) preventing LISTSERV from deleting the user, or because the list was configured with "Subscription= By owner" and the owner manually added the victim after the arrival of the undo request.
