In which case, as others have already suggested, I would set
Allow Form Tags = disarm
This is very simple and just breaks the form so it doesn't work any
more. "disarm" isn't a bad idea for any of those settings (the ones that
say you can use "disarm") as it still lets the message through, just
with the nasty bits broken.

It gives a very good description of all the configuration options and
talks about rulesets. I have posted the contents list here before, it
will be in the archive somewhere.
