Well, a first step would be to put a spam checker in rc.local.r00 or
rc.local.r10 (and enable the one yiu ise in rc.custom) so the obvious spams
are dropped before reaching the rest of the processing in rc.request. The spam
filter I use is not a harsh one but it doesn't need to be for these purposes.
If you still get some bogus requests through that trigger the help-file then
you can tune the rules in rc.request (for instance I removed the signature
scoring rule
*  3^0 ^^(.+$)*^([	 ]*$)*--
since it was getting triggered once and awhile by bogus requests.

You can be more draconian and only allow "help" to work for those already
subscribed.
