I want to enforce a text/plain posts policy, so I looked at this faq entry.

On it's face, it looks ok, but it comes at the problem backwards, which 
is hard to maintain, and makes enforcement problematical. That's because 
it lists the things to block, allowing what's not blocked to pass, which 
means when a new content type comes along, which it will, that we want 
to block, it will get onto the list until we explicitly block it.

Like good firewall design, it's better to block everything, and then 
only open holes for what you want to pass through. Then when a new 
content type comes along, it's automatically blocked, unless we 
expressly permit it. This is much safer.

How can I impliment my policy in this fashin, instead of how faq 3.10
