[lug] More Spam Please?

[John E. Koontz]

Just discovered an "unfilterable" piece of spam.  It was in html format and 
had been salted at random intervals with strings of <k...> where ... is 
random characters, and the length of k... was 15.  Not quite sure what the 
mechanics were, but perhaps it takes advantage of some anomaly of the kbd 
directive.  I filter it out with a filter on opening-angle-bracket k.   I 
haven't experimented with this further.
