The list of valid HTML tags is finite. You could try something like:
rawbody BOGUS_HTML_TAG /<\/(?<!(list|of|valid|tags|...)>)[a-z]+>/i
Here is where additive scoring would be of benefit. I wouldn't want to
score high on a handful of bogus tags, but a dozen or more should score
fairly high.
N.B.: I'm still having trouble wrapping my brain around zero-length
assertions - does the above look right?
