That makes sense. That would mean a person would have to be really quick to
post
a message and then delete it, right? (Unless their server was veerrrry slow?)

Very true.

Once a message propagates, most other news servers do not honor cancel messages
because they have encountered problems with bogus ones from trolls and the
like.
