Yeah. How come the "cancel message" command doesn't really do anything?

Because people got into wars of sending cancel messages for varous
other people's messages, and for spam, and for all messages in a
group, and so forth, and muddied the waters so badly that many servers
stopped honoring cancel messages. (Most of the spam control is now
done via nocem messages, which unlike the original cancel
architecture, are authenticated.)
