No, you didn't. Cancel messages are ignored by most NNTP servers,
If that were the case, news.admin.net-abuse.usenet would be pretty useless.
(People run cancel bots to remove spam in newsgroups automatically.)
The issue here is instead that Google Groups, which "lorlarz" used for their
trolling, does _not_ issue Cancel control messages when they are deleted in
the archive (and ignores them when in their newsfeed), and *maybe* "lorlarz"
has yet to understand what Usenet is and how it works. They could start
with said:
because they're trivial to forge.
So that would be a design decision made with disregard of the fact that
social problems cannot be solved with technology. However, if Cancel-Lock
was implemented by a server, trivial forging would not be possible.
Once you post something to Usenet, it's there forever.
That would depend on how much time passed between the posting and the
attempt to remove it.
