Thanks

I've been seeing that as well. They seem to all begin with <style> as
well, to keep that crap from going through mail client HTML parsers.
You can probably exploit the fact that nobody is ever going to write a
style block that doesn't match /[{}]/, but I haven't been able to
experiment yet with any rules.
I wouldn't recommend going the more general route of counting invalid
HTML tags, simply due to the enormity of trying to maintain such a rule
over time.
