invalid html warfare

[John McCain]

imho, I think the days of using code-level html to identify spam are gone.  I 
think the only way statistical filters are going to continue to be effective 
is if they see the message exactly as a human would.  I've seen a great deal 
of statistical filter evasion such as the examples I cited.  The best case 
scenario right now seems to be that the filter will still catch the message, 
but our databases will gradually degrade with garbage data such as 
<gmurfoophead>, assuming we are maintaining the training database.

I am beginning to wonder how practical it would be to ban html e-mail for my 
domain.
