Looks like the spammer's solution to the detection of their "insert random
punctation" approach is to insert random letters instead.  It's highly
likely that this approach is going to generate a *lot* of uncommon letter
sequences, so I'd look to trigger on that.  IIRC someone has already
produced set of regular expressions based rules for letter sequences that
do not occur in English, but I can't locate it on Google.  Anyone got a
link, because I think it may be time to add it to the collection...

In the meantime I integrated the Tripwire rules pointed out by Thomas Kinghorn and others. Now I'll wait and see... Maybe you should do the same?
