1 - Preamble

This document, posted monthly, list the nocems currently published
on the "news.lists.filters" group.
It does not deal with nocems published in a local hierarchy.
The aim is to publicize existing general nocems so that server
administrators can decide which nocems they wish to apply or not.

2 - Definition

NoCeM (pronounced No See 'Em) is a modern solution for managing spam.

Rather than issuing a "cancel" on a spam message that most servers will
reject, we generate a message in the "news.lists.filters" group called
"nocem", which contain the message(s) to be deleted.

Each nocem is signed with a gpg key to guarantee its authenticity.

The manager of each server is free to apply these nocems or not,
unlike global cancels, nothing is imposed.

3 - NoCeM or Cancel?

- Using nocems requires the server administrator to modify its configuration
to accept them. Otherwise, the nocem does nothing on the server.
It's a simple text message.

- Cancel, on the other hand, is accepted by default by the server
configuration. It's up to the server administrator to modify his config
to refuse certain types of cancels. This is not always easy.

For example, the news.usenet.ovh server refuses cancels from miakibot
because of past abuse. But the server configuration had to be modified
for this. Servers with little administration or little knowledge of "fr"
specificities generally keep the default config.

Reminder: general NoCeMs are published in news.lists.filters.

This is false, you just hate the maintainer of the miakibot because he was
hosted by Alphanet that you destroyed.

I can produce the list of more than 4000 past abusive cancels of the
miakibot on judicial requisition.

I can produce a list of your rogue cancels of my messages on
fr.usenet.abus.d, did you tell that to everyone ?

Lie
Another one from you.

But you were "the masked avenger" who deleted messages from a member
of "fufa" (the committee that manages groups creation/deletion
requests in the fr hierarchy).

In fact you are not only a troll, you are a malicious person :-(

So you can confirm that this FAQ, which is not even a FAQ because no one
asked you any question as you don't know anything about usenet, is just a
way to destroy some people's reputation, especially Marc Schaefer* and
Olivier Miakinen, who can't defend themselves because they don't read this
group ?

I let the readers of this group judge, maybe they don't care, but maybe
they use your NoCems or believe you but one day they will find out what a
bad person you are. EOT.

*Who made better FAQs BTW.
