To cancel someone's posts, is the "Control: cancel" header sufficient?

It's an act of tough love to cancel a no-coder's posts. They should
be practicing their CW instead of goofing off on usenet. Qrz.com
practices tough love, and so should the rest of us.

I've been lovingly cancelling Mark Morgan's posts, but not all of them
have gone away yet. I'm a little rusty on the use of cancel control
messages, but I think I've got them formatted correctly. The subject
line doesn't really have to contain "cmsg cancel" does it? I see my
messages in control.cancel, so they must be propagating around the net
properly.

I gather a lot of newsservers don't recognize cancel messages at this
point, because individuals were using it for malicious reasons. At
the very least, they need the cancel message to come from a known
source, such as a group dealing with pyramid schemes to make money.

And of course, if a newsserver doesn't recognize cancel messages,
the messages don't cancel.

If you don't know what you are doing, then you shouldn't be doing it.
It's my understanding that there is no newsgroup for control messages,
they simply propogate or not. It's been a while since I read up
on such messages.

The way to deal with the problem is to deal with the problem posters
ISPs. Because otherwise it will just take the war to another level.
It won't stop with the junk posts, and it won't stop with the junk
posts spreading over an increasingly wider spread of newsgroups, it
will just mean that if it works, then the junk posters may turn
around and start cancelling legit posts.
